摘要：
An effective synthesis of the 7-azaindole ring system has been developed from substituted 2-amino-3-vinyl pyridines. The methodology involves a novel cascade reaction sequence of controlled carbolithiation of the vinyl double bond, subsequent trapping of the intermediate organolithium with a suitable electrophile, followed by ring closure and dehydration.
