Abstract
The reaction between isocyanides 1,methyl anthranilate (2) and chloramines T (3a) or chloramines B (3b) occurred easily, in the presence of benzyltriethylammonium chloride to give the guanidines 4 which, upon heating, underwent a ring‐closure reaction to afford the title compounds 5.
期刊介绍：
The Journal of Heterocyclic Chemistry is interested in publishing research on all aspects of heterocyclic chemistry, especially development and application of efficient synthetic methodologies and strategies for the synthesis of various heterocyclic compounds. In addition, Journal of Heterocyclic Chemistry promotes research in other areas that contribute to heterocyclic synthesis/application, such as synthesis design, reaction techniques, flow chemistry and continuous processing, multiphase catalysis, green chemistry, catalyst immobilization and recycling.
