An easy and convenient direct synthesis of 2-azetidinones is described. The [2+2] cycloaddition reaction of
imines and carboxylic acids using 4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride (DMTMM) has
been employed to synthesize a variety of 2-azetidinones in high yields. The products were easily isolated because the byproducts
are highly soluble in water.
报道了一种简单便捷的2-氮杂环丁酮的直接合成方法。通过4-(4,6-二甲氧基-1,3,5-三嗪-2-基)-4-甲基吗啉氯盐(DMTMM)催化亚胺和羧酸的[2+2]环加成反应,实现了一系列2-氮杂环丁酮的高产率合成。产物易于分离,因为副产物在水中具有很高的溶解性。
