The photostimulated reaction of enolate anions of cyclic aromatic ketones such as substituted indan-1-ones and 3,4-dihydro-2H-naphthalen-1-one with o-iodoaniline in DMSO affords 1-, 2-, 3-, and 4-methoxy-5,10-dihydroindeno[1,2-b]indoles (34-40%), 1,2-, 1,4-, and 2,3-dimethoxy-5,10-dihydroindeno[1,2-b]-indoles (31-43%), and 1-, 2-, and 3-methoxy-5,11-dihydro-6H-benzo[a]carbazoles (42-61%) by the SRN1
在DMSO中,环状芳族酮(如取代的茚满1-酮和3,4-二氢2 H-萘-1-酮)的烯醇酸根阴离子与邻碘苯胺的光刺激反应可得到1、2、3和3。 4-甲氧基-5,10-二氢茚并[1,2- b ]吲哚(34-40%),1,2-,1,4-和2,3-二甲氧基-5,10-二氢茚并[1,2 - b ] -indoles(31-43%),和1-,2-,和3-甲氧基- 5,11-二氢-6- ħ -苯并[一个]咔唑(42-61%)由S RN 1机构一锅反应。
