Publication History
Publication Date:
17 May 2002 (online)
In this review, methods for the alkylation of aldehydes and ketones via formation of nitrogen derivatives such as enamines, metallated imines (imine anions), metallated N, N-dialkylhydrazones (N,N-dialkylhydrazone anions), dimetallated oximes (oxime dianions), and metallated O-methyloximes (O-methyloxime anions) are described. Scope, limitations, and advantages or disadvantages of the methods over comparative reactions of enolates are also mentioned. 1. Introduction 2. Enamines 2.1. Structure 2.2. Formation 2.3.
