Diastereoselective nucleophilic additions to vinyl phosphine oxides
Abstract
Some hydrogen, carbon, silicon, sulfur, nitrogen and oxygen nucleophiles react diastereoselectively with γ-oxygenated chiral vinyl phosphine oxides to give β-substituted phosphine oxides. Lithium N-benzyl-α-methylbenzylamide adds to prochiral vinyl phosphine oxides in the presence of trimethylsilyl chloride to provide, after protodesilylation, β-amino phosphine oxides as single diastereoisomers.
