Synthesis, Photophysical Characterization, and Anticancer Evaluation of Novel Furochromene Derivatives

ChemistryOpen, Volume 15, Issue 6, June 2026.
This is the first study on novel furochromene derivatives. A series of novel furochromen derivatives, namely (2E)‐1‐(6‐hydroxy‐4,7‐dimethoxy‐1‐benzofuran‐5‐yl)‐3‐arylprop‐2‐en‐1‐ones 4a–c, were synthesized via the Knoevenagel condensation of 6‐hydroxy‐4,7‐dimethoxybenzofuran‐5‐ylethanone 2 with various aromatic aldehydes.

Antimicrobial Benzopyrans from the Receptacle of Sunflower

Bioscience, Biotechnology, and Biochemistry, 1996
The antimicrobial substances in sunflower (Helianthus annuus) were investigated. Two antifungal benzopyran derivatives, 6-acetyl-2,2-dimethyl-1,2-benzopyran (1) and 6-acetyl-7-hydroxy-2,2-dimethyl-1,2-benzopyran (2), were isolated from the ethanol extract of sunflower receptacles.

Synthesis of benzofurans and benzopyrans

, 2002
Syntheses of 2,3-dihydrobenzofurans and 3,4-dihydrobenzopyrans normally involve several stages, therefore efficient syntheses of these compounds are desirable. A number of 3,4-dihydrobenzopyrans derivatives were prepared in one pot syntheses. The reaction is thought to proceed through cation intermediates, involving allylic cations generated by the ...
