Absolute Stereochemistry of Yeast Reduction Products from 2-(3', 4'-Dimethoxy-cinnamyl)-2-methylcyclopentane-1, 3-dione

Abstract

The absolute stereochemistry of yeast reduction products 2s and 2a from 2-(3', 4'-dimethoxy-cinnamyl)-2-methylcyclopentane-1, 3-dione (1) was investigated. The results from several spectral studies and chemical correlations enabled their absolute configurations to be concluded as (2S, 3S) and (2R, 3S), respectively.
