Abstract

The invention comprises benzoquinolizine compounds of the general formula <FORM:0999091/C2/1> and their optical enantiomorphs, wherein R1 is an alkyl group of from one to four carbon atoms, R2 is a lower alkoxy or a hydroxy group, and R3 and R4 are methyl or ethyl groups or together form a methylene group, together with a process for their preparation by condensing a ketone of formula <FORM:0999091/C2/2> with a (lower alkoxycarbonylmethylene)triarylphosphorane to give a compound of the above formula in which R2 is a lower alkoxy group, and if desired hydrolysing the product to yield the corresponding acid. The compounds are useful as intermediates for the synthesis of emetine. to. Specifications 999,092 and 999,096 are referred
