4H-Thieno[3,4-c]pyrrole (4) was synthesised from the azide (8) by intramolecular 1,3-dipolar cycloaddition followed by acid-catalysed 1,3-dipolar cycloreversion of the dihydrotriazole intermediate (9); the crystal structure of one of the products formed on trapping (4) with N-phenylmaleimide has been determined.
通过分子内的1,3-偶极环加成,然后酸催化的二氢三唑中间体(9),由叠氮化物(8)合成4 H-噻吩并[3,4- c ]吡咯(4);已经确定了用N-苯基马来酰亚胺捕获(4)时形成的产物之一的晶体结构。
