The first synthesis of 3-(dichloroacetyl)chromone from 3-(dimethylamino)-1-(2-hydroxyphenyl)propen-1-one and dichloroacetyl chloride is described. The reaction of electron-rich aminoheterocycles with 3-(dichloroacetyl)chromone provides a set of diverse fused pyridines bearing the CHCl2-substituent at the α-position of the pyridine core. Subsequent hydrolysis leads to the formation of annulated α-(formyl)pyridines
描述了由3-(二甲基氨基)-1-(2-羟基苯基)丙烯-1-酮和二氯乙酰氯首次合成3-(二氯乙酰基)色酮。富电子的氨基杂环与3-(二氯乙酰基)色酮的反应提供了一组不同的稠合吡啶,其在吡啶核的α-位带有CHCl 2-取代基。随后的水解导致环状的α-(甲酰基)吡啶的形成。 3-(二氯乙酰基)色酮-4 H -1-苯并吡喃-4-酮-杂环胺-稠合吡啶-环化反应
