Application of 15456-86-7, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15456-86-7, Name is 4-Bromo-1,2-dihydropyridazine-3,6-dione, molecular formula is C4H3BrN2O2. In a Article，once mentioned of 15456-86-7
The synthesis of 4-methoxy-, 4-amino-3-chloro-, and 4-amino-1-(2,3- dideoxy-beta-D-glycero-pentofuranosyl)pyridazin-6-one nucleosides, 6, 19 and 20 is described. The synthesis of 3,4-dichloropyridazin-6-one (10) was accomplished in 44% overall yield using bromomaleic anhydride (17) as the starting material. The condensation of the silylated base of 10 with the halogenose 12 in the presence of trimethylsilyl triflate as a catalyst afforded a mixture of 3,4-dichloro-1-(3,5-di-O-p-toluoyl-2-deoxy-beta-D- erythro-pentofuranosyl)pyridazin-6-one (13) in 67% and its alpha-anomer 14 in 12% yield, respectively. A series of 3′-sulfonate esters were prepared to explore the synthesis of 3-chloro-4-hydroxy-1-(3-azido-2,3-dideoxy-beta-D- erythro-pentofuranosyl)pyridazin-6-one (32) via 6,3-anhydronucleoside analogues. Compounds 15, 19 and 20 were evaluated against human immunodeficiency virus, human cytomegalovirus, and herpes simplex virus type 1 but were inactive.
We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 15456-86-7, and how the biochemistry of the body works.Application of 15456-86-7
