Absolute stereochemistry of yeast reduction products from 2-(3',4'-dimethoxy-cinnamyl)-2-methylcyclopentane-1,3-dione.
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.
