Furo[2,3-d]pirimidinų sintezė ir savybės / Sinthesys and chemical properties of furo[2,3-d]pirimidines

Vaitiulionytė, Diana 13 June 2006 (has links)
We report herein on the results of N- and O-alkylation of 5-cyano-2-methylsulfanyl-4(3H)- pyrimidinone with 4-substituted ω-bromoacetophenones. Synthesized N-(phenacyl)-4- pyrimidinones and 4-(phenacyloxy)pyrimidines with suitable substituents in pyrimidine ring are versatile synthons for the preparation of fused pyrimidine heterocycles. Chemical properties of new furo[2,3-d]pyrimidines were investigated. The structure of synthesized compounds was confirmed by data of 1H NMR, IR and UV spectra.
