The side reaction of the Curtius reaction was studied and a urine by-product was isolated and characterized.b. Through the detailed study of the behavior of various N-acetyl phenylalanine methyl esters under the condition of the Bischler-Napieralski reaction, it was found for the first time that the formation of benzyl oxazole derivatives was a competitive approach with the normal B-N reaction. A convincing mechanism was suggested and a rule governing the reaction was summarized.c.

一、基于Bischler-Napieralski反应设计了以苯丙氨酸衍生物为原料的路线，在这条路线的研究中，主要取得了以下结果：、建立了一条以芳香醛和丙二酸单甲酯为原料，通过缩合、氢化、Curtius等反应制备苯丙氨酸甲酯的通用合成路线，对其中的缩合反应条件及Curtius反应中的副反应进行了深入的研究，利用这条路线合成了四个芳环取代的苯丙氨酸单甲酯衍生物。
