2'-Deoxy-2'-methylene-6-azauridine (5) and 2'-deoxy-2'-methylene-6- azacytidine (8) have been synthesized via a multi-step procedure from 6- azauridine. 2'-Deoxy-2'-methylene-5-azacytidine (14a) and 2'-deoxy-2'- methylene-3-deazaguanosine (19a) and their corresponding α-anomers (14b and 19b) have been synthesized by the transglycosylation of 3',5'-O-(1,1,3,3- tetraisopropyldisiloxane-1,3-diyl)-2'-deoxy-2'-methyleneuridine (12) with silylated 5-azacytosine and silylated N2-palmitoyl-3-deazaguanine, respectively, in the presence of trimethylsilyl trifluoromethanesulfonate as the catalyst in anhydrous dichloroethane, followed by separation of the isomers and deprotection of the blocking groups. These compounds were tested for cytotoxicity against B16F10, L1210, and CCRF-CEM tumor cell lines and for antiviral activity against HIV-1, HSV-1, and HSV-2.

Paragraph 0080-0081; 0083-0084, (2020/08/09)
The invention belongs to the field of medicine synthesis, and provides a 2-deoxy-D-ribose derivative (III). When the derivative (III) is used for preparing decitabine, the stereoselectivity is good, and the yield is high. The invention provides a preparation method of the derivative. The preparation method comprises the following steps: step a, carrying out oxygen methylation on 1-position hydroxyl of 2-deoxy-D-ribose; and step b, protecting hydroxyl groups at positions 3 and 5, and further carrying out sulfonation on 1-position oxymethyl. The method is simple and convenient to operate, free of special equipment, good in product purity, high in yield and suitable for industrial production.
