One-step construction of carbazoles by way of the palladium-catalyzed double N-arylation reaction and its application to the total synthesis of murrastifoline-A
摘要:
The one-step construction of N-substituted carbazoles by way of the Pd-catalyzed double N-arylation reaction of primary amines with 2,2′-dibromobiphenyl is described. Aryl and aliphatic amines including tert-butylamine and a protected glucopyranosylamine were effectively transformed into the corresponding N-substituted carbazoles. The first total synthesis of murrastifoline-A, a biscarbazole alkaloid, based on this methodology is also presented.
