Abstract: 4H-4-Oxo-3-(R-vinylene)chromene derivatives and 3-(R-methylene)phthalide derivatives have been prepared by condensation reactions (R = 2H,5H-2-oxo-5,5-dimethyl-3-R⁵-4-furyl; 2H-2-oxo-6-dimethyl-3-R5-5,6-dihydropyran-4-yl; 2H-2-oxo-3-R⁵-4-chromenyl; R5 = CN, CONH₂, CO₂C₂H₅,[GRAPHICS].Some of the prepared compounds were tested for a variety of biological activities (for herbicidal, fungicidal, growTh-regulating activity, for antifungal activity against human pathogenic dermatophytes and micromycetes, and also for their possible anti-HIV activity).
