A new method of synthesis of 3-substituted thieno[3,2-b][1]benzothiophenes based on a halogen dance process was developed. The cycloaddition reaction of the title compound with dimethyl acetylenedicarboxylate leads to the formation of a complex mixture of products resulting from a series of consecutive reactions of the primary adduct.
一种基于卤素舞蹈过程的合成3-取代噻吩[3,2-b][1]苯并噻吩的新方法已经开发。标题化合物与二甲基乙烯二羧酸酯的环加成反应导致形成一种复杂的产物混合物,这些产物是由初级加合物的一系列连续反应产生的。
