A synthesis of the thieno[2′,3′(3′,2′ or 3′,4′):5,6]azocino[2,1-a]isoindole-7,13-diones 6a-c was developed from N-thienylethylphthalimides 3a-c using a Wittig reaction followed by a Friedel-Crafts cyclization of acetic acid derivatives 5a-c. Reduction of ketones 6a-c into alcohols 7a-c was stereo specific.
噻吩并的合成[2',3'(3',2'或3',4'):5,6]吖辛因并[2,1-一个]异吲哚7,13-二酮图6A-C是从开发N-噻吩基乙基邻苯二甲酰亚胺3a-c使用Wittig反应,然后进行乙酸衍生物5a-c的Friedel-Crafts环化。将酮6a-c还原成醇7a-c是立体特异性的。
