Dianions from simple N-tbutyl benzylic-type carbamates are readily formed with alkyllithium bases and undergo alkylation with a variety of electrophiles. Both secondary and tertiary α-oxo carbanions are easily accessible. DIBAL cleavage of the carbamate provides a high yield, general synthesis of alkylated benzylic alcohols.
