Aldol reactions with erythrulose derivatives: Stereoselective synthesis of differentially protected syn-α,β-dihydroxy esters

Boron enolates of 1-O-silylated erythrulose 3,4-acetonides prepared with Brown's chloro-dicyclohexylborane/tertiary amine system have been shown to react with achiral aldehydes in a highly stereoselective way to yield a 1,2- syn/1,3-syn stereoisomer. Thro

Erythrulose as a multifunctional chiron: Highly stereoselective boron aldol additions

We have investigated the formation of various metal enolates of 1-O- silylated erythrulose 3,4-acetonides. We were able to prepare boron enolates using Brown's dicyclohexylboron chloride / tertiary amine system. When these enolates were allowed to react w
