Paragraph 0094-0096, (2022/01/12)
The invention provides a synthesis method of a (1 beta, 2 alpha, 4 beta) halogenated nucleoside compound, and belongs to the field of organic synthesis. The synthesis method comprises the following steps of dissolving a compound 1 and a chiral phosphoric acid small-molecule catalyst in a solvent to obtain a mixed solution, adding an additive and a halogen source into the mixed solution, and carrying out an olefin asymmetric halogen cyclization reaction to prepare the (1 beta, 2 alpha, 4 beta) halogenated nucleoside compound as shown in a formula I. The synthesis method is simple and convenient in process, suitable for various reaction substrates and wide in application; and the synthesis method has high stereoselectivity on the beta-nucleoside compound and low cost, and the obtained beta-nucleoside compound has the advantages of high yield, high purity and very excellent effect. Meanwhile, the synthesis method is environment-friendly due to no use of a metal catalyst and the like. The synthesis method disclosed by the invention solves the technical problem of preparing the (1 beta, 4 beta) nucleoside compound in the prior art, can be used for efficiently preparing the (1 beta, 4 beta) nucleoside compound, and has a good application prospect.

A novel synthesis of AZT has been achieved from two commercial available products acetaldehyde and D-mannitol. The originality of the synthesis consists of using the powerful monovinylogation reagent, the 2-lithio-1-trimethylsiloxyethylene, and to introduce the thymine moiety and to build the furanose ring in the same and last step.
