EFFICIENT SYNTHESIS OF NOVEL TRICYCLIC BENZOXAZINE DERIVATIVE VIA RING OPENING OF EPOXIDE ALONG THE MP AND DFT STUDIES OF STRUCTURAL, SPECTROSCOPIC (IR, RAMAN, UV-VIS), THERMODYNAMIC, ORBITALS AND NLO PROPERTIES OF DESIRED TRICYCLIC BENZOXAZINE DERIVATIVE

A highly efficient synthesis of structurally diverse ortho-acylphenol–diindolylmethane hybrids 3 using carboxylic acid-activated chromones as versatile synthetic building blocks is reported here for the first time, through 1,4-nucleophilic addition and followed by a decarboxylation and pyrone ring opening reaction process.
