Abstract: An efficient synthetic route to antiviral 2?,3?-dideoxy-2?,3?-didehydro-nucleosides, such as 2?,3?-dideoxy and 2?- or 3?-deoxyribo-nucleoside analogs, from available precursors is disclosed, with the option of introducing functionality as needed. In one embodiment, a method for the preparation of ?-D and ?-L-2?,3?-dideoxy-2?,3?-didehydro-nucleosides is described that includes: activating a compound of structure (1) wherein B is a pyrimidine or purine base and Y is O, S or CH2 with an acyl halide of the formula X—C(?O)R1, X—C(?O)C(R1)2OC(?O)R1 or X—C(?O)OR1 (wherein X is a halogen, and each R1 is independently hydrogen, lower alkyl, alkyl, aryl or phenyl); reducing the resulting compound with a reducing agent to form a 2?,3?-dideoxy-2?,3?-didehydro-nucleoside; and optionally deprotecting the nucleoside. The haloacylation of the first step can form the 2?-acyl-3?-halonucleoside, the 3?-acyl-2?-halonucleoside, or a mixture thereof.

Abstract: The present invention is directed to a process for the preparation of a compound of formula (X-a) or a pharmaceutically acceptable salt form thereof, wherein: R1 is selected from the group consisting of: C1-5 alkyl substituted with 0-5 R1a, —(CH2)r—C3-10 cycloalkyl substituted with 0-5 R1a, and —(CH2)r-aryl substituted with 0-5 R1a. Compounds of Formula (X-a) are macrocyclic molecules containing anti-succinate residues which inhibit metalloproteinases such as aggrecanase, and the production of tumor necrosis factor (TNF). The anti-succinates are formed by an Ireland Claisen rearrangement of a silyl ketene acetal which proceeds with high stereoselectivity.
