An “One-Pot” Synthesis of Substituted 3-Benzoylamino-5-oxo-5, 6, 7, 8-Tetrahydrocoumarins

Abstract
A new simple “one-pot” synthesis of some 3-benzoylamino-5-oxo-5, 6, 7, 8-tetrahydrocoumarins from 1, 3-cyclohexanediones, hippuric acid, acetic anhydride and triethyl orthoformate or other one-carbon synthetic equivalent is described.
