Abstract

Abstract α-Phosphoramidolithium substituted allylic carbanions are used as homoenolate reagents with benzophenone and give regioselectively α-or γ-hydroxyalkylation products. Replacement of lithium by magnesium leads to γ substitution almost exclusively. Acidic hydrolysis of the adducts is a novel route to γ-lactol.
