arboxylic acid with acetic anhydride and dimethyl acetylenedicarboxylate gave 5-substituted derivatives of dimethyl 2,3-dihydro-1H-pyrrolizine-6,7-dicarboxylate and derivatives of dimethyl 5-(2-thienyl)pyrrolo[1,2-c]thiazole. Reduction of 2 with lithium aluminum hydride gave the diols 3a, 3b, 3c and 3d. These diols yielded the corresponding diacetates 4 by treatment with acetic anhydride. The bis(methylcarbamates)
用乙酸酐和乙炔基二羧酸二甲酯处理N-(2-呋喃基)脯氨酸或N-thenoyl脯氨酸和N-(2-thenoyl)噻唑烷-4-羧酸,得到5,取代的2,3-二氢-1H-吡咯啉二甲基衍生物-6,7-二羧酸酯和5-(2-噻吩基)吡咯并[1,2-c]噻唑二甲基的衍生物。用氢化铝锂还原2得到二醇3a,3b,3c和3d。这些二醇通过用乙酸酐处理得到相应的二乙酸酯4。用适当的异氰酸酯获得双(甲基氨基甲酸酯)5a,5b,5c和5d以及双(异丙基氨基甲酸酯)6b和6c。合成1-取代的吡咯烷嗪,将1-乙酰氧基化合物7b和7c进一步转化为1-羟基和1-氧代类似物。盐酸对1-乙酰氧基衍生物的作用得到3H-吡咯烷酮。对白血病L1210体内,几种双(烷基氨基甲酸酯)的抗白血病活性进行了评估。化合物5c和5d显示出与丝裂霉素相当的良好的抗白血病活性。
