The synthesis of cyclopropyl- and cyclobutyl-substituted α-aminophosphonates by three-component microwave-assisted reaction of cyclopropanecarbaldehydes, benzylamine, and diethyl phosphite in the presence of cadmium iodide as catalyst has been developed.

A skeletal rearrangement of dihalogenospiropentanes in the presence of alkyllithium reagents has been systematically studied using a number of gem-dibromospiropentanes. The scope and limitations of this carbenoid rearrangement are outlined and its mechanism is discussed. (c) 2006 Elsevier Ltd. All rights reserved.
