Desulfonylation of indoles and 7-azaindoles using sodium tert-butoxide

Chaulet, Charlotte,Croix, Cécile,Basset, Joan,Pujol, Maria-Dolores,Viaud-Massuard, Marie-Claude

, p. 1481 - 1484 (2010)

A mild method for the desulfonylation of N-indoles and N-azaindoles is described. Deprotection is carried out under basic conditions, using sodium tert-butoxide in dioxane. Several functionalized indoles and 7-azaindoles were efficiently deprotected by this method, which is mild enough to be used to deprotect compounds including functions that are known to be sensitive to acidic or basic conditions.
