The present invention relates to the synthesis of 2′-deoxy-&bgr;-L-thymidine, 2′-deoxy-&bgr;-L-uridine and 2′-deoxy-&bgr;-L-cytidine, and their derivatives, such as the 3′-O-acyl or 3′,5′-O-diacyl prodrugs, including the 3′-O-L-aminoacyl and 3′,5′-O-L-diaminoacyl prodrugs, and particularly the 3′-O-L-valinyl and 3′,5′-O-L-divalinyl prodrugs.
本发明涉及2'-脱氧-β-L-胸苷、2'-脱氧-β-L-尿苷和2'-脱氧-β-L-胞苷的合成,以及它们的衍生物,如3'-O-酰基或3',5'-O-二酰基前药,包括3'-O-L-氨基酰和3',5'-O-L-二氨基酰前药,特别是3'-O-L-缬氨酰和3',5'-O-L-二缬氨酰前药。
