Synthesis of 1,3-dioxin-4-ones having chiral hydroxyalkyl groups at the 6-position by means of baker's yeast reduction and their uses for epc synthesis
摘要:
Prochiral methyl ketones connected with 6-(4-oxo-1,3-dioxinyl) group directly or through methylene chain (1-3) gave, by treatment with fermenting baker's yeast, the corresponding (S)-alcohols which served as synthons for a variety of enantiomerically pure compounds.

A novel biocatalytic system to access a wide variety of β‐hydroxydioxinones from β‐ketodioxinones employing commercial engineered ketoreductases has been developed. This practical system provides a remarkably straightforward solution to limitations in accessing certain chemical scaffolds common in β‐hydroxydioxinones that are of great interest due to their diversification capabilities. A few highlights
