Abstract:
The diastereoselectivity of the addition of several organometallic reagents to the carbonyl group of protected
- and
-erythrulose derivatives has been investigated. Tertiary alcohols are stereoselectively formed, the diastereomeric ratio being markedly dependent on the reagent type, solvent and temperature.
