Total chemical synthesis of 4'-hydroxymethylnucleosides with an additional modification in a sugar residue was developed. The synthesis was made by condensation of corresponding protected sugars and nucleic bases with subsequent deprotection. In such a way 3'-azido- and 3'-amino-3'deoxy-4'-hydroxymethylribonucleosides, 2',3'-anhydroribo- and 2',3'-anhydrolyxo-4'-hydroxymethylribonucleosides as well as 3'-deoxy-4'hydroxymethylribollucleosides were prepared. At concentrations up to 100 mu M none of them inhibited reproduction of human immunodeficiency virus type 1 in H9 and PBL cells as well as human herpes simplex virus type 2 and human cytomegalovirus in vero cells.
