d-Isomannide in synthesis: asymmetric Diels–Alder reactions with novel homochiral bis-imine Cu2+-catalysts
摘要:
The synthesis of a set of novel homochiral bis-imine ligands 4 derived from D-isomannide 6, and their application in the Cu2+-catalyzed asymmetric Diels-Alder reaction of cyclopentadiene and N-tert-crotonoyloxazolidinone I is reported. (C) 2002 Elsevier Science Ltd. All rights reserved.
