N → C3 migration of dichlorophosphino group in the phosphorylation of N-unsubstituted indole with phosphorus trichloride
Abstract
A N → C3 migration of the dichlorophosphino group has been revealed in the phosphorylation of unsubstituted indole with phosphorus trichloride. Several 3-phosphorylated NH-indole derivatives have thus been obtained and N-acylation of one of the products has been performed. © 2009 Wiley Periodicals, Inc.
