The synthesis of sterically hindered primary, secondary and tertiary alcohols is reported. An unusual monoalkylation/reduction occurs on treatment of a fully alpha-substituted methyl carboxylate with t-BuLi. A mechanism not involving a ketone intermediate but a beta-H abstraction from t-BuLi prior to or after alkylation is proposed.
