Stereoselective synthesis of aryl γ,δ-unsaturated β-hydroxyesters by ketoreductases

The biocatalytic reduction of aryl γ,δ-unsaturated-β- ketoesters was evaluated utilizing 24 different commercially available ketoreductases. In all cases, both (R) and (S)-enantiomers of γ,δ-unsaturated β-hydroxyesters were synthesized by one or more keto

RHODIUM(II) ACETATE-CATALYZED REACTION OF ETHYL 2-DIAZO-3-OXOPENT-4-ENOATES: SIMPLE ROUTES TO 4-ARYL-2-HYDROXY-1-NAPHTHOATES AND β,γ-UNSATURATED ESTERS. THE DIANION OF ETHYL 4-(DIETHYLPHOSPHONO)ACETOACETATE AS A PROPIONATE EQUIVALENT

Rhodium(II) acetate-catalyzed decomposition of ethyl 2-diazo-3-oxopent-4-enoates results in the formation of either 4-aryl-2-hydroxy-naphthoates or β,γ-unsaturated esters.In the latter transformation, the dianion of 4-(diethylphosphono)acetoacetate functi
