摘要：

New chiral diimino and diamino ligands derived from alpha -D-mannose and alpha -D-glucose are described. The ligands are obtained by introducing the appropriate nitrogen functions at C(2) and C(3) of the sugar rings. The ability of the new chelates to promote the asymmetric copper(I)-catalysed cyclopropanation of styrene has been investigated. The nature of both the sugars and the chelates is crucial in determining the enantioselectivity of the reaction. (C) 2001 Elsevier Science Ltd. All rights reserved.
