An halogen migration of iodine during the metalation of pyrimidines has been highlighted and a mechanism is proposed. An unusual halogen-lithium exchange with LTMP has been observed. A new synthetic route to Leshmaniacides using metalation and cross coupl

A new series of achiral pyrimidine derivatives based on nifedipine-like structure was designed and synthesized. These pyrimidyl derivatives contained hydrazine, hydrazones, acetohydrazide, differently substituted benzylidene functionalities, benzosulfohyd

Abstract A series of hybrids comprising of 5-cyanopyrimidine and quinoline moiety were synthesized and tested for in vitro antiplasmodial activity against NF54 and Dd2 strains of Plasmodium falciparum. Hybrid bearing m-nitrophenyl substituent at C-4 of py

(Chemical Equation Presented) The Suzuki-Miyaura reaction of some 4,6-dichloropyrimidines bearing methylthio-, methyl-, amino-, cyano-, formyl-, and nitro groups in positions 2 and/or 5 of the pyrimidine ring with arylboronic acids has been investigated. Influence of palladium catalyst, ligand, base, and solvent on the reaction outcome was studied. The reaction was found to give the corresponding 4,6-diarylpyrimidines in reasonable yields using Pd(OAc) 2/PPh3/K3PO4 or Pd(PPh 3)2Cl2/K3PO4 as catalyst systems.

4-Chloro-2-methylthio -6-phenylpirimidine-5-carbonitrile (II) reacts with hydrazine hydrate to yield the 2,4-dihydrazino derivative (IIId).Compound IIId reacts with nitrous acid to give ditetrazolopyrimidine (VI) and with carbon disulphide to form pyrazolo-s-triazolopyrimidine (VII).The reaction of II with phenylhydrazine affords directly the pyrazolo-pyrimidinederivative (IV).Also, compound II reacts with anthranilic acid to form 2-methylthio-4-phenyl-6-(o-carboxyphenylamino)pyrimidine-5-carbonitrile IIIe) which can bee cyclised into 1-methylthio-10-oxo-3-phenyl-10-pyrimidoquinazoline-4-carbonitrile (IX) by heating with acetic anhydride.Key words: Methylthiopyrimidine; chloropyrimidine; hydrazinopyrimidine; pyrimidoquinazolinone.
