The first example of the formation of a seven-membered ring by way of intramolecular-catalyzed amination of saturated C-H bonds is reported (Du Bois reaction). The influence of various structural parameters was studied, and it was shown that the unexpected regioselectivity observed in nitrogen-containing systems could be rationalized by conformational factors. These results open the way to innovative
报道了通过分子内催化的饱和CH键的胺化形成七元环的第一个例子(Du Bois反应)。研究了各种结构参数的影响,结果表明,可以通过构象因素使在含氮体系中观察到的意外区域选择性合理化。这些结果为一般合成多官能化哌啶的创新策略开辟了道路。
