Study on reactivity of pentacoordinate bicycloazastannoxides. I. Aldol condensation with aldehydes
Abstract
The condensation of α-carbanions formed from pentacoordinate bicycloazastannoxides with aldehydes was investigated. Nine novel organotin(IV) complexes with β-hydroxy-a-amino acids were synthesized. Their structures were determined by IR, 1H NMR, 119Sn NMR spectroscopy, MS, and elemental analyses. The reaction mechanism is discussed. © 1996 John Wiley & Sons, Inc.
