Synthesis and reactivity of substituted 3-([(Trifluoromethyl)sulfonyl]oxy)-1H-indole-2-carboxylate in palladium-catalyzed reactions
摘要:
Palladium-catalysed Suzuki and Stille reactions of substituted 3-indolyltriflate afforded the corresponding 3-substituted indoles. By contrast, the Heck reaction of allyl alcohol with such triflates gave 2-allyloxy-3-oxoindole derivatives rather than the 3-substituted indole products as a result of a nucleophilic attack on an acyliminium intermediate.

Indolic triflate reacted with 1,2-diamines to afford pyrazino[2,3-b]indole or indolo[2,3-b] quinoxaline. Carbon nucleophiles such as malonate derivatives also reacted with indolic triflate in absence of palladium catalyst to afford 2-(3-oxo-2,3 -dihydro-1H-2-indolyliden) malonate derivatives.
