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.
简单的N-叔丁基苄基型氨基甲酸酯的阴离子容易与烷基锂碱形成,并通过各种亲电试剂进行烷基化。仲和叔α-氧代碳负离子都很容易获得。氨基甲酸酯的DIBAL裂解提供了高产率的烷基化苄醇的一般合成。
