Ester and method for production thereof as well as hydrolysis process and determination of optical purity using this ester

摘要

This invention relates to a novel ester which presents as (CF 1) and a method for the production of the same as well as a process for hydrolysis and a method for the determination of an optical purity using this ester, and the object thereof is to provide an intermediate for the synthesis or various natural products, which has high stability, and the optical purity of which can readily be determined, according to the esterification of 1-oxo-5-hydroxymethyl-2-cyclohexene which is unstable to acids and alkalis. <IMAGE> (CF1)
