design that involves two key cyclization steps. First, the iodine(III)-mediated reaction of a series of N-benzylpentynamides leads to the generation of the 5-aroylpyrrolidinone skeletons. Finally, after reduction of the generated ketone group into the corresponding carbinol, the effect of a number of different acidic conditions was studied to assist the second cyclization step that occurs through an
通过涉及两个关键环化步骤的合成设计,可实现一系列10-芳基取代的吡咯并异喹啉的非对映控制制备。首先,碘(III)介导的一系列N-苄基戊炔酰胺的反应导致生成5-芳基吡咯烷二酮骨架。最后,在将生成的酮基还原为相应的甲醇后,研究了许多不同酸性条件的影响,以协助通过芳族亲电取代过程发生的第二个环化步骤。对这一步骤的立体化学过程的研究使我们得出结论,它是通过具有非常高(> 95%的抗)非对映异构控制的S N 1机制发生的。
