DETAILED DESCRIPTION OF THE INVENTION
DEFINITIONS AND GENERAL TERMINOLOGY
Reference will now be made in detail to certain embodiments of the invention, examples of which are illustrated in the accompanying structures and formulas. The invention is intended to cover all alternatives, modifications, and equivalents which may be included within the scope of the present invention as defined by the claims. One skilled in the art will recognize many methods and materials similar or equivalent to those described herein, which could be used in the  practice of the present invention. The present invention is in no way limited to the methods and materials described herein. In the event that one or more of the incorporated literature, patents, and similar materials differs from or contradicts this application, including but not limited to defined terms, term usage, described techniques, or the like, this application controls.
It is further appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one skilled in the art to which this invention belongs. All patents and publications referred to herein are incorporated by reference in their entirety.
As used herein, the following definitions shall apply unless otherwise indicated. For purposes of this invention, the chemical elements are identified in accordance with the Periodic Table of the Elements, CAS version, and the Handbook of Chemistry and Physics, 75th Ed. 1994. Additionally, general principles of organic chemistry are described in “Organic Chemistry” , Thomas Sorrell, University Science Books, Sausalito: 1999, and Smith et al., “March’s Advanced Organic Chemistry” , John Wiley &Sons, New York: 2007, the entire contents of which are hereby incorporated by reference.
The grammatical articles “a” , “an” and “the” , as used herein, are intended to include “at least one” or “one or more” unless otherwise indicated herein or clearly contradicted by the context. Thus, the articles are used herein to refer to one or more than one (i.e. at least one) of the grammatical objects of the article. By way of example, “a component” means one or more components, and thus, possibly, more than one component is contemplated and may be employed or used in an implementation of the described embodiments.
The term “comprise” is an open expression, it means comprising the contents disclosed herein, but don’t exclude other contents.
“Stereoisomers” refers to compounds which have identical chemical constitution, but differ with regard to the arrangement of the atoms or groups in space. Stereoisomers include enantiomer, diastereomers, conformer (rotamer) , geometric (cis/trans) isomer, atropisomer, etc.
“Enantiomers” refers to two stereoisomers of a compound which are non-superimposable mirror images of one another.
“Diastereomer” refers to stereoisomers with two or more centers of chirality and whose molecules are not mirror images of one another. Diastereomers have different physical properties, e.g. melting points, boiling points, spectral properties or biological activities. Mixture of diastereomers may separate under high resolution analytical procedures such as electrophoresis and chromatography such as HPLC.
Stereochemical definitions and conventions used herein generally follow S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., “Stereochemistry of Organic Compounds” , John Wiley &Sons, Inc., New York, 1994.
Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. When describing an optically active compound, the prefixes D and L, or R and S are used to denote the absolute configuration of the molecule about its chiral center (s) . The prefixes d and l or (+) and (-) are employed to designate the sign of rotation of plane-polarized light by the compound, with (-) or l meaning that the compound is  levorotatory. A compound prefixed with (+) or d is dextrorotatory. A specific stereoisomer may be referred to as an enantiomer, and a mixture of such stereoisomers is called an enantiomeric mixture. A 50: 50 mixture of enantiomers is referred to as a racemic mixture or a racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process.
Any asymmetric atom (e.g., carbon or the like) of the compound (s) disclosed herein can be present in racemic or enantiomerically enriched, for example the (R) -, (S) -or (R, S) -configuration. In certain embodiments, each asymmetric atom has at least 50 %enantiomeric excess, at least 60 %enantiomeric excess, at least 70 %enantiomeric excess, at least 80 %enantiomeric excess, at least 90 %enantiomeric excess, at least 95 %enantiomeric excess, or at least 99 %enantiomeric excess in the (R) -or (S) -configuration.
Depending on the choice of the starting materials and procedures, the compounds can be present in the form of one of the possible stereoisomers or as mixtures thereof, such as racemates and diastereoisomer mixtures, depending on the number of asymmetric carbon atoms. Optically active (R) -and (S) -isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques. If the compound contains a double bond, the substituent may be E or Z configuration. If the compound contains a disubstituted cycloalkyl, substituents of the cycloalkyl may have a cis-or trans-configuration.
Any resulting mixtures of stereoisomers can be separated on the basis of the physicochemical differences of the constituents, into the pure or substantially pure geometric isomers, enantiomers, diastereomers, for example, by chromatography and/or fractional crystallization. Cis and trans isomers are diastereomer.
Any resulting racemates of final products or intermediates can be resolved into the optical antipodes by methods known to those skilled in the art, e.g., by separation of the diastereomeric salts thereof. Racemic products can also be resolved by chiral chromatography, e.g., high performance liquid chromatography (HPLC) using a chiral adsorbent. In particular, enantiomers can be prepared by asymmetric synthesis.
As described herein, compounds disclosed herein may optionally be substituted with one or more substituents, such as are illustrated generally below, or as exemplified by particular classes, subclasses, and species of the invention. It will be appreciated that the phrase “optionally substituted” is used interchangeably with the phrase “substituted or unsubstituted” . In general, the term “substituted” refers to the replacement of one or more hydrogen radicals in a given structure with the radical of a specified substituent. Unless otherwise indicated, an optionally substituted group may have a substituent at each substitutable position of the group. When more than one position in a given structure can be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at each position. Specifically, “one or more” before an example refers to 1, 2, 3, 4, 5, 6, 7, 8, 9 or 10. wherein substituents of compounds disclosed herein include, but are not limited to, deuterium, fluoro (F) , chloro (Cl) , bromo (Br) , iodo (I) , cyano (CN) , hydroxy (OH) , nitro (NO 2) , amino (NH 2) , carboxy (COOH) , alkyl, alkoxy, alkoxyalkyl, alkoxyalkoxy, alkoxyalkylamino, aryloxy, heteroaryloxy, heterocyclyloxy, arylalkoxy, heteroarylalkoxy, heterocyclylalkoxy, cycloalkylalkoxy, alkylamino, alkylaminoalkyl, alkylaminoalkylamino, cycloalkylamino, cycloalkylalkylamino, alkylthio, haloalkyl, haloalkoxy, hydroxy-substitued alkyl, hydroxy-substitued alkylamino, cyano-substitued alkyl, cyano-substitued alkoxy, cyano-substitued alkylamino, amino-substitued alkyl, alkylacyl, heteroalkyl, cycloalkyl, cycloalkenyl, cycloalkylalkyl, heterocyclyl, heterocyclylalkyl, heterocyclylacyl, aryl, arylalkyl, arylamino, heteroaryl, heteroarylalkyl,  heteroarylamino, acylamino, sulfonyl, aminosulfonyl, and the like.
