A method was developed for the synthesis of new fused 3-alkyl-substituted derivatives of thieno[3,2- d ]pyrimidin-4(3 H )-ones based on 11-(2-furyl)-8,8-dimethyl-7,10-dihydro-8 H -pyrano[3′′,4′′:5′,6′]pyrido[3′,2′:4,5]-thieno[3,2- d ]pyrimidin-4(3 H )-one via nucleophilic substitution in the pyrimidine ring. A series of fused 4-amino-substituted 11-furylthieno[3,2- d ]pyrimidine derivatives was also synthesized from the corresponding 4-chloro derivative.

Abstract:
Continuing our research in the field of new heterocyclic compounds, herein we report on the synthesis and antitumor activity of new amino derivatives of pyrido[3’,2’:4,5](furo)thieno[3,2-d]pyrimidines as well as of two new heterocyclic systems: furo[2–e]imidazo[1,2-c]pyrimidine and furo[2,3-e]pyrimido[1,2-c]pyrimidine. Thus, by refluxing the 8-chloro derivatives of pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidines with various amines, the relevant pyrido[3’,2’:4,5]thieno(furo)[3,2-d]pyrimidin-8-amines were obtained.

The preparation of a number of pyrimidinethiols and (substituted) thiopyrimidines has been carried out. The reaction of 5-acetylamino-2-aminopyrimidine-4,6-diol with phosphorus penta -sulfide in pyridine gave 5-amino-2-methylthiazolo[5,4-d]pyrimidine-7-thiol which was used to prepare several additional novel pyrimidine derivatives. Hydrolysis of the 4-carboxymethylthio derivative by using 5M hydrochloric acid gave 2,5-diamino-6-mercaptopyrimidin-4-ol hy -drochloride whilst hydrolysis of 2-methyl-7-methylthiothiazolo[5,4-d]pyrimidin-5-amine gave the corresponding 4-hydroxy derivative.

Synthesis of a new 4-hydrazinopyrazolo[3,4- d]pyrimidine was achieved via heating (4,6-dithioxo-1 H-pyrazolo[3,4- d] pyrimidin-3-yl)acetonitrile with hydrazine hydrate. Reactions of the latter product with thiophene-2-carbaldehyde and ethyl hydrazonoacetoacetate analogues afforded the corresponding hydrazone and pyrazole derivatives, respectively. Similarly, condensation of 2-[6-(benzylsulfanyl)-4-hydrazino-1 H-pyrazolo[3,4- d]pyrimidin-3-yl]acetonitrile with thiophene-2-carbaldehyde and ethyl hydrazonoacetoacetate analogues gave the respective hydrazone and pyrazolone derivatives.

The chromeno and pyrimidine classes compounds include a variety of hybrid molecules displaying diverse biological actions. Although they have been examined for many years, these compounds are still of interest due to their facile chemical transformations. The presence of chromeno and pyrimidine structural motifs in many drugs, prompted us to investigate the antioxidant features of compounds 5-(7-bromo-2,4-dioxo-1,3,4,5-tetrahydro-2H-chromeno[2,3-d]pyrimidin-5-yl) pyrimidine-2,4,6(1H,3H,5H)-tri-one (CP-1) and 8,9- ihydroxy-2H-chromeno[2,3-d]pyrimidine-2,4(3H)-dione (CP-2).
