Abstract
The one step transformation of esters into secondary alcohols (70-80% yield s) has been performed with a Grignard reagent in the presence of calcium or zinc borohydride. Under the same conditions, vinylic Grignard reagents gav e gamma,delta-unsaturated alcohols in good yields through three successive reactions : addition to the eater carbonyl, then conjugate addition and, fi nally reduction).
