Stepwise and one-pot cross-coupling-heteroannulation approaches toward 2-substituted C5-, C6-, and C7-nitroindoles

Sun, Li-Ping,Huang, Xiang-Hong,Dai, Wei Min

, p. 10983 - 10992 (2007/10/03)

A general and efficient synthesis of 2-substituted C5-, C6-, and C7-nitroindoles has been established. Starting from commercially available 2-amino nitrophenols, C5-, C6-, and C7-nitroindoles were synthesized via the stepwise Pd-catalyzed cross-coupling o
