Chemistry of 3-carbonyl-2-methyl-4-oxo-4H-1-benzopyrans

“…Unsubstituted and various substituted 2′-hydroxyacetophenones, [35][36][37] 3,6-diacetyl-5-hydroxyindole 38 and benzofuran 15b 39 have been converted into the corresponding 3-benzoylchromones. Ac 2 O-DMSO 40 and Ac 2 O in DMAP/pyridine, 41 instead of Ac 2 O-AcONa, have also been used for the conversion of many 2′-hydroxy-ω-benzoylacetophenones to chromones analogous to 3.…”
