- Synthesis method of beta-nicotinamide mononucleotide
-
The invention discloses a synthesis method of beta-nicotinamide mononucleotide, and relates to the technical field of drug synthesis. The synthesis method mainly comprises the following steps of S1, mixing and reacting nicotinamide, hexamethyldisilazane and a catalyst I in a reaction kettle to obtain silanization-protected nicotinamide; S2, adding tetraacetyl ribose, a solvent, a catalyst II and methanol for reaction so as to generate nicotinamide triacetyl riboside; S3, adding methanol and n-propylamine to generate nicotinamide riboside; S4, adding trimethyl phosphate and phosphorus oxychloride to generate beta-nicotinamide mononucleotide; and S5, separating and purifying the beta-nicotinamide mononucleoside acid. According to the invention, a plurality of continuous steps are controlledto be carried out in one reaction container, and the steps of separating and purifying an intermediate are avoided, so that the method has the advantages of high yield and high production efficiency.

- Stereoselective synthesis of nicotinamide β-riboside and nucleoside analogs
-
A stereoselective synthesis of β-anomers of nicotinamide riboside (NAR), its deamidated analog (NaR), and of a nicotinamide C-methylated riboside derivative (NA3′-C-MeR) was developed. The β-anomers of N-ribofuranosylnicotine-3-carboxamide (β-NAR) and its nicotinic acid analog (β-NaR) were obtained by stereoselective synthesis via glycosylation of the presilylated bases under Vorbruggen's protocol. A NAR analog, methylated in position 3 of the ribosylic moiety, is also reported.
