The formal [3+2] cycloaddition of 1,3,5-triaryl-1,3,5-triazinanes with donor-acceptor cyclopropanes has been found to provide pyrrolidines in good to excellent yields under mild reaction conditions. Preliminary mechanistic investigation indicates that this formal [3+2] cycloaddition reaction proceeds through competing SN1 and SN2 pathways.
已经发现,在温和的反应条件下,将1,3,5-三芳基-1,3,5-三嗪酮与供体-受体环丙烷进行正式的[3 + 2]环加成反应可提供吡咯烷类化合物。初步的机理研究表明,这种正式的[3 + 2]环加成反应是通过竞争性的S N 1和S N 2途径进行的。
