Synthesis of 2-Substituted 5-(1,2,3-Selenadiazol-4-yl)furan-3-carboxylic Acids Esters

Аннотация

A series of semicarbazones have been obtained from 2-substituted 5-acetylfurancarboxylic acid esters. When oxidized with selenium dioxide in acetic acid, 5-(1,2,3-selenadiadiazol-4-yl)furan-3-carboxylic acid esters bearing a functional group in position 2 of the furan ring have been formed.
