Harutyunyan, A. A. published the artcileOne-Pot Three-Component Condensations of 2,6-Diaminopyrimidin-4(3H)-one, Aromatic Aldehydes, and Naphthols. Synthesis of Isomeric Benzochromeno[2,3-d]pyrimidines, Synthetic Route of 86-51-1, the main research area is benzochromenopyrimidine preparation; diaminopyrimidinone benzaldehyde naphthol three component cyclocondensation.
One-pot three-component reactions of 2,6-diaminopyrimidin-4-(3H)-one with aromatic aldehydes and 1- or 2-naphthol afforded benzo[7,8]chromeno[2,3-d]pyrimidine I (R = 3-Br, 3-NO2, 4-PhCH2O, etc.) and benzo[5,6]chromeno[2,3-d]pyrimidine II (R1 = H, 2-F, 2-OH-3-OMe, etc.) derivatives, resp. In both cases, the heterocyclization involved substitution of the 6-amino group of 2,6-diaminopyrimidin-4-(3H)-one by hydroxy group of naphthol and closure of 4H-pyran ring, whereas no alternative benzopyrimidoquinoline derivatives were formed.
Russian Journal of Organic Chemistry published new progress about Benzaldehydes Role: RCT (Reactant), RACT (Reactant or Reagent). 86-51-1 belongs to class isoquinoline, name is 2,3-Dimethoxybenzaldehyde, and the molecular formula is C9H10O3, Synthetic Route of 86-51-1.
