An efficient method for the preparation of N-formyl-imide via amidine using propylphosphonic anhydride (T3P®)
摘要:
An efficient method for the preparation of N-formyl imide via amidine using propylphosphonic anhydride (T3P (R)) has been described. Using this method many aryl, hetero aryl, alkyl as well as amino acid imides were synthesized in high yields. (C) 2015 Elsevier Ltd. All rights reserved.
Facile access to <i>N</i>-formyl imide as an <i>N</i>-formylating agent for the direct synthesis of <i>N</i>-formamides, benzimidazoles and quinazolinones
N-Formamide synthesis using N-formyl imide with primary and secondary amines with catalytic amounts of p-toluenesulfonic acid monohydrate (TsOH·H2O) is described. This reaction is performed in water without the use of surfactants. Moreover, N-formyl imide is efficiently synthesized using acylamidines with TsOH·H2O in water. In addition, N-formyl imide was successfully used as a carbonyl source in the
