One-pot synthesis of benzofuryl-substituted semicarbazides under microwave irradiation

A series of asymmetric semicarbazides was synthesized by reactions of 2-benzofuran isocyanate, which was prepared by Curtius rearrangement from 2-benzofuroyl azide with acid hydrazide under microwave irradiation using a one-pot procedure. Comparing to the conventional method, this method has the advantages of mild conditions, easy handling, and high yield. Copyright Taylor & Francis Group, LLC.

Synthesis of benzofuryl substituted unsymmetrical ureas under microwave irradiation

A series of 2-benzofuryl substituted unsymmetrical ureas were synthesized by reactions of benzofuroyl isocyanate, which was prepared from benzofuroyl azide by Curtius rearrangement, with various aromatic amines, 2-amino-5-(benzo-2-furyl)-1,3,4-thiadiazole, and 2-amino-5-aryloxymethylene-1,3, 4-thiadiazoles under microwave irradiation. Compared to conventional methods, this synthesis has the advantages of mild reaction conditions, easy handling, and high yields. The products have been characterized by analytical and spectral (IR and 1H NMR) data.
