A STEREOSELECTIVE SYNTHESIS OF (Z)-α,β-DISUBSTITUTED ACRYLATES
A new route for (Z)-α,β-disubstituted acrylate is described which is made up of 1) stereoselective reduction of ketones 3 and 2) conversion of the resulting syn-2 into (Z)-1.
Preparation of β-Hydroxy-α-phenylthio Esters via Condensation of Aldehydes with α-Phenylthio Ester Enolate Anions
The lithium enolates of α-phenylthio esters 5 react with aldehydes 6 to give good yields of diastereomeric aldol products 7 and 8 provided that anhydrous zinc chloride is first added to the enolate solution.The threo or erythro nature of several of the al
