The synthesis of pyrrolidino[2,1-b]thieno[3,2(2,3)-f][3]azepinediones 7a,b and pyrrolidino[2,1-b]-[1]benzothieno[3,2(2,3)-f][3]azepinediones 7c,d are described starting from thiophenes or [1]benzothio-phenes acetic acids. Their selective reduction using triethylsilane led to the corresponding azepinones 17a-d.
吡咯烷酮[2,1- b ]噻吩并[3,2(2,3)-f ] [3]氮杂二酮7a,b和吡咯烷酮[ 2,1 - b ]-[1]苯并噻吩并[3,2(描述了从噻吩或[1]苯并噻吩-苯乙酸开始的2,3)-f ] [3]氮杂二酮7c,d。它们使用三乙基硅烷的选择性还原得到相应的a庚酮17a-d。
