The reaction of 5-amino-3-(arylamino)-1H-pyrazole-4-carboxamides 1a,b with acetylacetone 2 and arylidenemalononitriles 5a-c yielded the pyrazolo[1,5-a]-pyrimidine derivatives 4a,b and 7a-f respectively. On the other hand, Schiff bases 9a,b and 12a-j were obtained upon treatment of carboxamides 1a,b with isatin 8 and some selected aldehydes 11a-e. The newly(More)
The reaction of 3-mercapto-6-methyl-1, 2, 4-triazin-5 (2H)-one 1 with dimethyl 2a and trimethyl phosphite 3a at 100 C in absence of solvent yields the dimeric product 4 and while the alkylated products 5 and 6 are obtained for reaction with 3a. Methylation of 1 by methyl iodide gives alkylated product 5. Reaction of 1 with diethyl 2b and triethyl phosphite(More)
Due to the importance of biological activities of 1,2,4-triazine derivatives, in this manuscript, ten of newly synthesized compounds containing 1,2,4-triazine moiety were prepared. Anticancer and antimicrobial activities of some selected synthesized compounds were screened. Chalcone derivatives 6, 7 were synthesized via reaction of Mannich base 2 in acetic(More)
