摘要：

Whereas chromones are usually cleaved by amines, 3-(aryliminomethyl) chromones undergo nucleophilic addition with aromatic primary amines to give 2-amino-3-(arylaminomethylene)chroman-4-one derivatives. The 3-(aryliminomethyl) group also facilitates addition to the system of a variety of alcohols and thiols, and certain thiol adducts can be cyclised to thiazepine derivatives. The action of manganese dioxide on 3-(aryliminomethyl)chromones leads to 3-(arylaminomethylene)chroman-2,4-diones.
