and DABCO in chloroform gave the corresponding [1,2]dithiolo[4,3-b]indole-3(4H)-thiones 5 by the addition of triethylamine in high yield. 1,2-Dithiole-3-thiones 5 underwent cycloaddition with one or two DMAD equivalents to afford either 2-(3-thioxo-1,3-dihydro-2H-indol-2-ylidene)-1,3-dithioles 10 or fused 4,5-dihydrothiopyrano[3,2-b]indoles 9.
用S 2 Cl 2和DABCO在氯仿中处理N-取代的2-甲基-1 H-吲哚1,得到相应的[1,2]二硫代[4,3 - b ]吲哚-3(4 H)-硫酮5。高产率地添加三乙胺。1,2-二硫代-3-硫酮5与一或两个DMAD等效物进行环加成反应,得到2-(3-硫代-1,3-二氢-2 H-吲哚-2-亚烷基)-1,3-二硫代10或稠合的4,5-二氢硫代吡喃并[3,2- b ]吲哚9。
Selectfluor facilitated bridging of indoles to bis(indolyl)methanes using methyl <i>tert</i>-butyl ether as a new methylene precursor
A novel, green and efficient method is developed for the synthesis of methylene bridged bis(indolyl)methanes in good to excellent yields. The reaction employs methyl tert-butyl ether (MTBE) as the methylene source and selectfluor as an oxidizing agent. The scope and versatility of the methods have been successfully demonstrated with 48 examples. The metal-free transformation process is suitable for
