D. Alker et al., CARBAMATE DERIVED STABLE PRECURSORS FOR GENERATING CHIRAL AZOMETHINE YLIDS UNDER MILD CONDITIONS, Tetrahedron, 53(37), 1997, pp. 12671-12678
We describe the evolution of stable azomethine ylid precursors which a
void the need for an aldehyde in the ylid generation step. tert-Butyl
carbamate derivative (16) demonstrates comparable efficiency to the st
andard method of ylid generation and trapping, but permits use of mild
er conditions. (C) 1997 Elsevier Science Ltd.
