Homoaldol and aldol reactions from common enolates and oxiranes: Reaction of reductively generated chromium enolates through cationic rearrangement
Enolates generated from alpha-bromo esters by the reduction with "Bu6CrLi3" react with oxiranes to afford gamma-hydroxy esters and beta-hydroxy esters, depending on the Lewis acid used as a promoter.
