Diastereoselectivity in asymmetric allylations: The role of vicinal chirality in the allyl nucleophile for SE2′ reactions with aldehydes

Article abstract of DOI:10.1139/v03-168

A series of nonracemic homoallylic alcohols have been prepared by asymmetric allylation using the (R,R)-and (S,S)-1,2-diamino-1,2-diphenylethane bis-sulfonamide controller ligands for in situ formation of chiral B-allyl-1,3,2-diazaborolidines. Diastereofa
