Enantio- and diastereomerically pure threo-homoallylic alcohols via highly stereoselective reduction of α-methyl-β,γ-unsaturated ketones

Reduction of α-methyl-β,γ-unsaturated ketones with L-Selectride proceeded with high threo-selectivity to afford threo-β-methyl homoallylic alcohols of high enantio- and diastereomerical purities.
