General and efficient synthesis of indoles through triazene-directed c-h annulation

Wang, Chengming,Sun, Huan,Fang, Yan,Huang, Yong

, p. 5795 - 5798 (2013/06/27)

Unprotected indoles are prepared with the title method, which has a wide scope for alkynes. Excellent regioselectivity was accomplished for aryl-alkyl and alkyl-alkyl disubstituted acetylenes. This reaction features an unusual 1,2 rhodium migration and ring-contraction-triggered N-N bond cleavage. It allows rapid conversion of the reaction products into several functional molecules.
