Abstract

PURPOSE:To obtain a novel compound useful as a base for cosmetic, cosmetic retainer, antioxidant, etc. CONSTITUTION:A compound expressed by the formula (R1 is 4-30C alkyl, arylalkyl, alkenyl or arylalkenyl; R<2> is H, 1-30C alkyl or alkenyl). The compound by the formula is obtained by e.g. adding n-octylaldehyde, L-ascorbic acid, p-toluenesulfone hydrate, DMF and benzene to 5,6-0-oxtylidene-Lascorbic acid and reacting these components under reflux on heating while removing water produced by the condensation reaction out of the system by azetrope.

32,170.00 As mentioned above, the yield is further improved when the acetal form thereof, such as dimethyl acetal, is used instead of the aldehyde or ketone in the reaction with L-ascorbic acid. For example, by heating and refluxing a dimethyl acetal of an aldehyde or ketone and approximately equimolar amounts of L-ascorbic acid in an inert solvent such as DMF/hexane in the presence of an acid catalyst such as p-toluenesulfonic acid, Ascorbic acid acetal derivatives can be produced in higher yields than when using aldehydes or ketones. Examples are given below.
