Starting from [4,3-c] and [3,2-c] methyl chlorosulfonylthiophenecarboxylates the synthesis of ketones 7 and 8 is described. These compounds are the first two representatives of the new thieno[3,4-c] and thieno-[3,2-c][2,1]benzothiazepine ring systems. The formation of methyl 3-chlorosulfonylthiophene-2-carboxy-late is also revised.
从[4,3- c ]和[3,2- c ]甲基氯磺酰基噻吩羧酸酯开始,描述了酮7和8的合成。这些化合物是新的噻吩并[3,4- c ]和噻吩并- [3,2- c ] [2,1]苯并硫氮杂ring环系统的前两个代表。3-氯磺酰基噻吩-2-羧酸甲酯的形成也被修改。
