The reaction of aryl isothiocyanates with nonstabilized azomethine ylides generated in situ by various methods was studied. It was established that the use of N-(methoxymethyl)-N-(trimethylsilylmethyl)benzylamine in the presence of trifluoroacetic acid in the role of a catalyst led to the formation of (Z)-N-aryl-3-benzylthiazolidin-5-imines in 22–47% yields.

N-苄基偶氮甲亚胺叶立德与异硫氰酸芳基酯的反应：（Z）-N-芳基-3-苄基噻唑烷-5-亚胺的合成

研究了异硫氰酸芳基酯与通过各种方法原位生成的不稳定的甲亚胺基化物的反应。已经确定，在三氟乙酸的存在下，在催化剂的作用下使用N-（甲氧基甲基）-N-（三甲基甲硅烷基甲基）苄基胺导致形成（Z）-N-芳基-3-苄基噻唑烷-5-亚胺的产率为22–47％。
