The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 110553-27-0, Name is 2-Methyl-4,6-bis((octylthio)methyl)phenol, SMILES is OC1=C(CSCCCCCCCC)C=C(CSCCCCCCCC)C=C1C, in an article , author is Karimian, Azam, once mentioned of 110553-27-0, Quality Control of 2-Methyl-4,6-bis((octylthio)methyl)phenol.
Synthesis of A Novel Heterocyclic System of 3,8-Disubstituted-5H-Pyrimido[5′,4′:5,6][1,4]Thiazino[3,2-e][1,2,4]Triazine
The new compounds 6-methyl-8-morpholino-2Hpyrimido[5′,4′:5,6][1,4]thiazino[3,2e][1,2,4]triazin-3(5H)-one(3a)and 6-methyl-8-(piperidin-1-yl)-2Hpyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazin-3(5H)-one(3b)were obtained from cyclocondensation of 6-bromo-1,2,4-triazine-3,5(2H,4H)-dione(1)with appropriate 5-amino-6methylpyrimidine-4-thiol (2a, b)in dimethylformamide and in the presence of potassium carbonate under reflux. Reaction of compounds(3a, b)with phosphorous oxychloride gave 4-(3-chloro-6-methyl-5H-pyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazin-8-yl)morpholine(4a)and 3-chloro-6-methyl-8-(piperidin-1-yl)-5H-pyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazine(4b). Nucleophilic substitution of chlorine atom of compounds(4a, b)with typical secondary amines in DMF and K(2)CO(3)produced the new derivatives of the 3,8-disubstituted-5H-pyrimido[5′,4′:5,6][1,4]thiazino[3,2-e][1,2,4]triazine ring systems(5a-f). All the synthesized products were characterized and confirmed by their spectroscopic and microanalytical data.
