Abstract
Abstract (R) and (S) of 2-Methy1-3-oxa-5-(tert-butyldiphenylsilyloxyl)methy1pentanoate (4a. 6a) and (R) and (S) of 2-methy1-3-oxa-5-(tert-butyldimethylsilyloxyl)methylpentanoate (4b, 6b) were synthesized by the reaction of the preparative compounds (2a, 2b) with (R) and (S) methy1lactate (3, 4) in the presence of a silver (1) oxide catalyst (Method B). The title compounds are useful for the synthesis of different natural products such as epothilones.
