simple method for the generation and alkylation of diethyl lithiomaleate. These reactions proceed with complete retention of alkene geometry, providing a convenient method for the diastereoselective introduction of this useful four carbon synthon.

The paper describes a convenient method for the diastereoselective synthesis of trisubstitutedalkenesthrough the lithium amide mediated union of ketones and diethyl maleate. The reaction has been shown to proceed via a Michael Initiated- Condensation - Elimination (MICE) sequence.
