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. Heteroatom Chem 20:235–239, 2009; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/hc.20540

Abstract

A successive N C2 C3 migration of the dichlorophosphino group has been found to occur in phosphorylation of unsubstituted pyrrole with phosphorus trichloride. As a result of this migration, a number of hitherto unknown C-phosphorylated N-unsubstituted pyrroles have been obtained. © 2008 Wiley Periodicals, Inc.

Abstract

Isothiocyanatophosphonium salts bearing an aroxy group at the phosphorus atom have been obtained for the first time. As found, these compounds undergo an intramolecular heterocyclization to give hitherto unknown benzoxazaphosphininethiones or cyanoiminophosphoranes, according to the nature of the substituents on the aryl ring. © 2008 Wiley Periodicals, Inc.

Abstract

A study on the stepwise hydrolysis of hetarene- and cycloalkenecarboxamidophosphoryl dichlorides afforded the synthesis of hitherto unknown hetarene- and cycloalkene-carboxamidophosphoric acids as well as allowing the introduction of unsubstituted carbamoyl group in the molecules of pyrroles, indoles, indolizines, and some enamines.

6. Isocyanatophosphoric Acid Dichloride: A Novel Reagent for the Introduction of a Cyano Group into the Molecules of Electron-Rich Heterocycles and Enamines

Subjects
Indole test, chemistry.chemical_compound, Group (periodic table), Chemistry, Reagent, Organic Chemistry, Molecule, Organic chemistry, Indolizine, General Medicine, Medicinal chemistry, Catalysis, Pyrrole
Abstract

A new synthetic method is developed which enables a direct one-step introduction of a cyano group into electron-rich heterocyclic systems of the indole, pyrrole, and indolizine series, and also to enamines using isocyanatophosphoryl dichloride.
