Efficient syntheses of (E)-5-(2-Bromovinyl)-2'-deoxy-4'thiouridine; a nucleoside analogue with potent biological activity

(E)-5-(2-Bromovinyl)-2'-deoxy-4'-thiouridine (S-BVDU) is a potent antiherpesvirus agent and its use in gene therapy as an anticancer agent has recently been described. We here outline 2 efficient methods for the synthesis of S-BVDU. The decision as to which method is to be used depends upon the starting materials available but starting from BVU, an overall yield of β-nucleoside of 35% can be expected. From 5-ethyl-2'deoxy-4'- thiouridine, radical bromination using bromine will give a quantitative conversion to S-BVDU if unreacted starting material is recycled (50%) or using N-bromosuccinimide, a one step yield in excess of 80% can be obtained.

The synthesis and antiviral activity of some 4'-thio-2'-deoxy nucleoside analogues

Starting from benzyl 3,5-di-O-benzyl-2-deoxy-1,4-dithio-D-erythro-pentofuranoside (4), the following 2'-deoxy nucleoside analogues have been synthesized: 4'-thiothymidine (8), 3'-azido-4'-thio-deoxythymidine (10), and (E)-5-(2-bromovinyl)-4'-thio-2'-deoxy
