摘 要:主要研究了固体酸催化剂对氮杂环丙烷与异硫氰酸酯间的[3+2]环加成反应的催化效果,并对反应展开了一系列底物拓展。实验结果表明,在该催化体系下,反应都有不错的收率。并且通过催化剂重复性实验,也可以发现,经过多次重复利用的固体酸也可以起到有效的催化作用。In this research,an efficient,simple,and general route for the[3+2] cycloaddition reaction of aziridines with isothiocyanates been described using functionlized zeolite catalysis inair.Using SBA-15- PW as catalyst,a series of heterocycles were obtained from aziridines in good to high yields.Moreover, reusability study showed that the catalyst SBA-15-PW could be reused at least for 5 runs without losing significant catalytic activity after a simple washing.
