The first ring‐opening reaction of donor–acceptor cyclopropanes to give diamines is reported. For this reaction, a 1,3‐bisfunctionalization was developed using cyclopropanes, triazinanes, and Sc(OTf)3 as the catalyst, followed by treatment with acid. The reaction proceeds under very mild conditions and tolerates many functional groups. Moreover, a library of various 1,3‐diazepanes, which arise as intermediates
据报道,供体-受体环丙烷第一次开环反应生成二胺。对于该反应,使用环丙烷,三嗪酮和Sc(OTf)3作为催化剂开发了1,3-双官能度,然后用酸处理。反应在非常温和的条件下进行,并能耐受许多官能团。此外,还合成了各种1,3-二氮杂library的文库,这些文库是与供体-受体环丙烷进行的第一次正式氮杂[4 + 3]-环加成反应的中间体。
