Chemistry of 4-oxo-4H-1-benzopyran-3-carbonitrile

Abstract

The review article, primarily designed to complement an earlier one (J. Heterocycl. Chem. 2005Chem. , 42, 1035Chem. -1042, gives a comprehensive survey of the synthesis and chemistry of the title nitrile covering the literature published during 2005-2014.

Recent advances in the synthesis of 4H-chromen-4-ones (2012 − 2021)

“…The synthesis and reactivity of 2-acyl-4H-chromen-4-ones, 11 of 2-aryl-and 2-aryl-3-substituted 4H-chromen-4-ones, 12 of halo-4H-chromen-4-ones, 13 of 4-oxo-4H-chromen-3-carbaldehydes, 14 of 4-oxo-4H-chromen-3-carbonitriles 15 of 2-methyl-4-oxo-4H-chromen-3carboalkoxides, 16 of 4-oxo-4H-chromen-3-carboxylates and 4-oxo-4Hchromen-3-ylglyoxalates, 17 of electron-deficient 3-vinyl-4H-chromen -4-ones 18 and 4H-chromen-4-ones polyfluorinated in A-ring, 19 have been detailed in minireviews. The synthesis of furochromones, their transformation and biological activities has also reviewed.…”
