REACTIONS OF METHYL DERIVATIVES OF 2-PENTEN-5-OLIDE, 2-BUTEN-4-OLIDE, AND COUMARIN WITH DICARBOXYLIC ANHYDRIDES AND WITH 3-FORMYLCHROMONES UNDER THE PERKIN SYNTHESIS CONDITIONS

Abstract

4H-4-Oxo-3-(R-vinylene)chromene derivatives and 3-(R-methylene)phthalide derivatives have been prepared by condensation reactions (R = 2H,5AV-2-oxo-5,5-dimethyl-3-R5 -4-furyl; 2H-2-oxo 6,6-dimethyl-3-R-5,6-dihydropyran-4-yl; 2H-2-oxo-3-R5 -4-chromenyl; R5 = CN, CONH2> C02C2H5, н4сГ ^°— )• Some of the prepared compounds were tested for a variety of biological activities (for herbicidal, fungicidal, growth-regulating activity, for antifungal activity against human patho genic dermatophytes and micromycetes, and also for their possible anti-HIV activity)
