[摘要]：The synthesis of novel non-cross-linked polystyrene supported 2-phenylimino-2-oxazolidine is described, and its use as a chiral auxiliary in asymmetric alkylation reactions is demonstrated by the synthesis of several chiral amides (>96 % ee), Furthermore, recovery and recycling of the polymer-supported chiral auxiliary were successfully achieved without appreciable reduction in the yield or stereoselectivity. |
