New diastereoselective method for constructing a carbon chain by conversion of N,N′-dialkyl-N,N′-diacylhydrazines to threo-1,2-dicarboxylic acid derivatives
Abstract
A diastereoselective method is described for constructing a carbon chain by conversion of N,N′-dialkyl-N,N′-diacylhydrazines (1a–f) to dialkyldiamides of threo-1,2-dicarboxylic acids (3a–f).
