摘要:
The present invention relates to a novel synthetic process for the enriched preparation of substituted R(+)β-benzyl-γ-butyrolactone (1) as shown in the drawing wherein R1 and R2 independently or in combination represent the following groups: i.e. R1═R2═H, —OCnH2n+1 (where n=1 to 8); R1, and R2 together represents —O(CH2)mO— (where m=2 to 4)
