Nitrogen-15 labeled butyl 4,5,6,7-tetrahydro-2H-isoindoIe-1-carboxylate was prepared via butyl iso-cyanoacetate from 15N-glycine in an overall 46% yield. This bicyclic intermediate was converted into nitrogen-15 and carbon-13 labeled 2,3:7,8:12,13:17,18-tetrabutanoporphyrin, a useful model system for the sedimentary tetrahydrobenzoporphyrins.
通过异氰基乙酸丁酯从15 N-甘氨酸制备氮15标记的4,5,6,7-四氢-2 H-异二烯基-1-羧酸丁酯,总产率为46%。该双环中间体被转化为氮15和碳13标记的2,3:7,8:12,13:17,18-四丁烷卟啉,这是用于沉积四氢苯并卟啉的有用模型系统。
