We report here a multicomponent protocol to assemble several polycyclic dihydropyran-fused tetrahydroquinoline structures with excellent diastereoselectivity. This procedure employs simple feedstocks to accomplish a series of diverse structures, which is difficult to attain by traditional sequences.
                                    我们在这里报告了一个多组分协议,用于组装几个具有优异非对映选择性的多环二氢
吡喃稠合
四氢喹啉结构。该程序采用简单的原料来完成一系列不同的结构,这是传统序列难以实现的。
