Abstract

Reactions of 5-bromo-2-hydroxybenzaldehyde with cyanoacetic acid hydrazide derivatives in refluxing ethanol afforded some new chromene-based polyfunctionally substituted heteroaromatics. The antimicrobial activity of some of the obtained products was evaluated. The structures of the newly synthesized compounds were elucidated based on their elemental analyses and spectral data.
