Isocyanatophosphoryl dichloride as reagent for introduction of carbamoyl group into molecules of π-excessive heterocycles and enamines

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