Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 1194-22-5, is researched, SMILESS is CC1=NC(=CC(N1)=O)O, Molecular C5H6N2O2Journal, Journal of Heterocyclic Chemistry called Ylides of heterocycles. VII. Iodonium-, nitrogen-, phosphonium-, and sulfonium-ylides of pyrimidones, Author is Habib, Nargues Samuel; Kappe, Samuel, the main research direction is pyrimidinone ylide; iodonium ylide pyrimidinone; phosphonium ylide pyrimidinone; sulfonium ylide pyrimidinone; pyridinium ylide pyrimidinone; isoquinolinium ylide pyrimidinone.Electric Literature of C5H6N2O2.
Reaction of pyrimidinone I (R = OH; R1 = H, Me, Ph, R2 = H; R1 = R2 = Ph; R3 = H) with PhIO prepared in situ gave iodonium ylides I (R = O-, R3 = PhI+; II) in good yield. Thermal rearrangement of II gave I (R = OPh; R3 = iodo), which were deiodinated to give I (R = OPh, R3 = H). Treatment of II with pyridine, nicotinamide, isoquinoline, Ph3P, or thiophene gave the corresponding N, P, or S ylides. The pyridinium ylides were also prepared from I (R = OH, R1 = Br, Cl) which were prepared from II by treatment with HBr or HCl, resp.
