In a Article，once mentioned of 17285-36-8

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.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 17285-36-8 is helpful to your research.Synthetic Route of 17285-36-8

A library of iminolactones was prepared by esterification of several 2-hydroxyketones with a number of N-protected d- and l-alpha-amino acids. Some of the hydroxyketones were of terpenoid origin while others were obtained via synthesis. After N-deprotection of the intermediate esters, the free amines spontaneously underwent condensation with the ketone to form iminolactones. Esters of (1S,2S,5S)-2-hydroxypinan-3-one with both d- and l-alpha-amino acids were partially epimerized at the alpha-carbon atom to give a diastereomeric ester mixture. Only iminolactones of l-amino acids were formed after cyclization of (1S,2S,5S)-2-hydroxypinan-3-one, and correspondingly only d-amino acid iminolactones were formed after reaction with (1R,2R,5R)-2-hydroxypinan-3-one. The protocol thus enables inversion of the absolute configuration of amino acids. Some members of the prepared library of iminolactones displayed significant anti-proliferative effects toward three cancer cell lines (EL4, MCF7, PC3) with insignificant effect on non-malign cell lines (McCoy, MCF10A, NIH3T3). Thus, iminolactones appear to be potential lead structures for preparation of drugs selectively affecting proliferation of malign cell lines.
