Total synthesis of three natural phenethyl glycosides

Phenethyl glycosides having phenolic or methoxy functions at benzene rings are substances widely occurring in nature. This kind of compounds has been shown to have anti-oxidant, anti-inflammatory, and anticancer activities. However, some of them are not naturally abundant, thus the synthesis of such molecules is desirable. In this paper, natural phenethyl glycosides 3 and 4 were first totally synthesized from easily available materials with overall yields of 50.5% and 40.1%, respectively. And a new synthetic route to obtain natural phenethyl glycoside 2 in 46.2% yield was also described.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.category: Tetrahydropyrans, you can also check out more blogs about10343-06-3

4-METHYLUMBELLIFERYL 2-ACETAMIDO-2-DEOXY-alpha-D-GLUCOPYRANOSIDE, A FLUOROGENIC SUBSTRATE FOR N-ACETYL-alpha-D-GLUCOSAMINIDASE

Condensation of dimeric 3,4,6-tri-O-acetyl-2-deoxy-2-nitroso-alpha-D-glucopyranosyl chloride with 4-methylumbelliferone gave crystalline 4-methylumbelliferyl 3,4,6-tri-O-acetyl-2-deoxy-2-oximino-alpha-D-arabino-hexopyranoside.Acetylation of this adduct, reduction of the resulting crude O-acetyloxime with borane in oxolane, and acetylation gave the 3,4,6-tri-O-acetyl derivative of 4-methylumbelliferyl 2-acetamido-2-deoxy-alpha-D-glucopyranoside (1).A new sensitive assay of N-acetyl-alpha-D-glucosaminidase (EC 3.2.1.50) is made possible by fluorometric measurement of 4-methylumbelliferone liberated by enzymic hydrolysis of glycoside 1.Such assays are illustrated by results obtained with enzyme preparations from pig liver and human-blood serum.

Synthesis and use of glycosyl phosphites: An effective route to glycosyl phosphates, sugar nucleotides, and glycosides

An efficient and convenient synthetic route to glycosyl phosphites and phosphates has been developed that uses dibenzyl N,N-diethylphosphoramidite as a phosphitylating reagent. Glycosyl phosphites and phosphates of 2-acetamido-2-deoxy-D-galactose (GalNAc) (29), 2-acetamido-2-deoxy-D-glucose (GlcNAc) (30), D-galactose (Gal) (31), D-glucose (Glc) (32), D-mannose (Man) (33), L-rhamnose (Rha) (34), L-fucose (Fuc) (35), and N-acetylneuraminic acid (NeuAc) (41) were prepared by this procedure. Compounds 29 and 30 were obtained as alpha anomers exclusively, whereas compounds 31, 32, and 41 were obtained as beta anomers, and compounds 33 and 34, as alpha anomers, predominately. The phosphates are useful for the synthesis of sugar nucleotides, and the phosphites are effective glycosylation reagents.

Syntheses of potential metabolites of a potent kappa-opioid receptor agonist, TRK-820

Chemical syntheses of three kinds of potential metabolites of TRK-820, a potent kappa-opioid receptor agonist, were described. One of the potential metabolites 2, 17-N-dealkylated TRK-820, was synthesized starting from noroxycodone through 8 steps in 21% total yield. Glucuronidation of intermediate 10 and compound 1, the free base of TRK-820, was carried out stereoselectively to give 3-O-beta-D-glucuronides 15 and 16 in good yields, respectively. Syntheses of potential conjugated metabolites 3 and 4 were accomplished through 10 steps and 2 steps in 11% and 43% total yields, respectively.
