Abstract/Summary:
Oxetanocin A, isolated in 1986 from the fermentation broth of Baccilus megaterium, was the first reported, naturally occurring nucleoside that contained an oxetane as the sugar moiety. This novel nucleoside also demonstrated potent anti-viral activity against HSV-1, HSV-2, HCMV and HIV-1. Herein, we report the first synthesis of a psico-nucleoside analog of oxetanocin A by utilizing the reactivity of SelectfluorRTM , an electrophilic fluorine source, with an alpha-methylene-oxetane.;alpha-Glycosphingolipids (GSLs) have found much attention for their ability to modulate immune responses. The interest in this field continues to grow. Pharmalogically active GSLs and labeled GSLs are essential for studying their role immune responses and can lead to the development of new approaches to treating cancer and other autoimmune diseases. This thesis describes the synthesis of GSLs designed to aid in the investigation of NKT cell stimulation.
