A phosphine-catalyzed [3 + 3] cyclization strategy between para-quinamines and HCHO Morita–Baylis–Hillman (MBH) carbonates was discovered, delivering a series of highly functionalized hydroquinoline derivatives in moderate to good yields and excellent diastereoselectivity. Moreover, mechanistic insights, gram-scale experiments, and synthetic manipulations of the products were also discussed.
发现了对苯二胺与HCHO森田-贝利斯-希尔曼(MBH)碳酸酯之间的膦催化的[3 + 3]环化策略,从而以中等至良好的收率和优异的非对映选择性提供了一系列高度官能化的氢喹啉衍生物。此外,还讨论了机理见解,克级实验和产品的合成操作。
