| Research Abstract |
1) First we tried the glycosylation reaction using glycosyl donors having fluorous leaving groups. Although the derivatives of mannosyl fluoride and mannosyl Nphenyltrifluoroacetimidate gave the corresponding glycosides in good yields under homogeneous conditions [Et2O-NovecTM(2:1)], no glycoside was observed by TLC under fluorous biphasic system [organic solvent-FluorinertTM FC-72].
2) Next, we designed and synthesized the derivative of mannosyl Nphenylpentadecafluorooctanoimidate as a new fluorous glycosyl donor. This new donor gave the glycoside in high yield only under homogeneous conditions similar to that of N-phenyltrifluoroacetimidate.
3) Finally, we found the 6- O-Hfb (fluorous protecting group) derivative of mannosyl trichloroacetimidate without a fluorous leaving group gave the corresponding glycoside in good yield under fluorous biphasic conditions [dichloromethane-FC-72].
