Synthesis of Quinoline-Based Thieno-Seleno-Phenylquinazolinones

Abstract

The synthesis of quinoline-substituted phenylquinazolinones containing sulfur and selenium is described. These molecules were isolated from a series of reactions of 2-phenyl-4H-3,1-benzoxazin-4-one with 2-chloro, 2-thieno, and 2-selenoquinoline-3-carbaldehyde hydrazones. The structure of the isolated compounds has been elucidated on the basis of IR, ¹ H NMR, mass spectral, and elemental analysis data.
