Porphyrins with fused nitronaphthalene and benzothiadiazole subunits have been synthesized by the “2 + 2” and “3 + 1” methodologies; the key pyrrolic intermediates were prepared by the base catalyzed condensation of dinitronaphthalenes or 4-nitro-2,1,3-benzothiadiazole with isocyanoacetates.
带有稠合的硝基萘和苯并噻二唑亚基的卟啉已通过“ 2 + 2”和“ 3 +1”方法合成。关键的吡咯中间体是通过二硝基萘或4-硝基-2,1,3-苯并噻二唑与异氰基乙酸酯的碱催化缩合制备的。
