Abstract

Abstract The one step transformation of esters into secondary alcohols (70--80% yields) has been performed with a Grignard reagent in the presence of calcium or zinc borohydride. Under the same conditions, vinylic Grignard reagents gave γ, δ-unsaturated alcohols in good yields through three successive reactions: addition to the ester carbonyl, then conjugate addition and, finally reduction).
