Patent number: 5914400Abstract: The present invention relates to a method of preparing BCH-189 and various analogs of BCH-189 from inexpensive precursors with the option of introducing functionality as needed. This synthetic route allows the stereoselective preparation of the biologically active isomer of these compounds, .beta.-BCH-189 and related compounds. Furthermore, the steochemistry at the nucleoside 4' position can be controlled to produce enantiomerically-enriched .beta.-BCH-189 and its analogs.Type: GrantFiled: June 7, 1995Date of Patent: June 22, 1999Assignee: Emory UniversityInventors: Dennis C. Liotta, Woo-Baeg Choi

Patent number: 5892025Abstract: A process for the resolution of a racemic mixture of nucleoside enantiomers that includes the step of exposing the racemic mixture to an enzyme that referentially catalyzes a reaction in one of the enantiomers. The nucleoside enantiomer (-)-2-hydroxymethyl-5-(5-fluorocytosin-1-yl)-1,3-oxathiolane is an effective antiviral agent against HIV, HBV, and other viruses replicating in a similar manner.Type: GrantFiled: July 14, 1998Date of Patent: April 6, 1999Assignee: Emory UniversityInventors: Dennis C. Liotta, Raymond F. Schinazi, Woo-Baeg Choi
