Chiral N-phosphonyl imine chemistry: new reagents and their applications for asymmetric reactions
摘要:
Novel chiral N-phosphonyl imines 2 have been designed and synthesized using chiral N-phosphoramide 1. These N-phosphonyl imines have been successfully utilized for asymmetric aza-Darzens reaction and asymmetric aza-Henry reaction. The C(2)-symmetric chiral auxiliary tolerates oxidation, is not sensitive to racemization and can be recycled for large scale synthesis. (c) 2008 Elsevier Ltd. All rights reserved.
