摘要：

Quinidine was found to catalyze the Michael addition of unprotected 3-substituted oxindoles to nitroolefins in excellent yield and moderate to good diastereoselectivity. Bifunctional quinidine derived thiourea catalyst 10 could catalyze this reaction to afford the major diastereomer in up to 85% ee.
