2-Selenocyanatobenzophenone reacts with hydroxylamine to give 3 - phenyl - 1,2 - benzisoselenazole N-oxide, the structure of which is indicated by polarographic reduction studies. The corresponding methyl and ethylketones react similarly but 3 - methyl - 2 - selenocyanato acetophenone yields 4,8 - dimethyl - 2 - imino - 2H -1, 3 - benzoselenazine 3-oxide. Benzoselenopheno[3,2-b]indole is formed under

pyrazino[2′,3′:4,5]selenopheno[3,2-b]indole and chromeno[3′,4′:4,5]selenopheno[3,2-b]indol-6-one, were prepared from the appropriate 3-aminoselenophen-2-carboxylates via a one-pot two-step procedure based on the Fischer indole synthesis. The present synthetic strategy includes the conversion of 3-aminoselenophen-2-carboxylates into 2-unsubstituted 3-aminoselenophenes, their C-2 protonation to form
一系列各种硒酚[3,2- b ]吲哚基化合物,包括2-芳基取代的硒酚[3,2- b ]吲哚以及苯并[4,5]硒酚[3,2-]衍生物b ] 吲哚、吡啶并[3′,2′:4,5]硒酚[3,2- b ]吲哚、吡嗪基[2′,3′:4,5]硒酚[3,2- b ]吲哚和色酚[ 3',4':4,5]硒酚[3,2 -b ]吲哚-6-酮,由适当的3-氨基硒酚-2-羧酸盐通过基于费歇尔吲哚的一锅两步法制备合成。目前的合成策略包括将3-氨基硒酚-2-羧酸盐转化为2-未取代的3-氨基硒酚,其C-2质子化形成硒酚-3( 2H )-亚胺阳离子,以及这些亚胺中间体与芳基肼的反应获得硒酚-3(2 H )-酮的芳基腙,然后对其进行费歇尔吲哚化,得到硒酚[3,2- b ]吲哚分子。
