The present invention relates to compounds of formula (I),
wherein R1, R2, R3, R4, R5 and R6 are as described herein, and their prodrugs or pharmaceutically acceptable salt, enantiomer or diastereomer thereof, and compositions including the compounds and methods of using the compounds.
The combined use of silanes (Et3SiH or PMHS) and I-2 as novel N-glycosidation reagents for the synthesis of bioactive oxathiolane nucleosides 3TC and FTC is reported. Both systems (working as anhydrous HI sources) were devised to act as substrate activators and N-glycosidation promoters. Excellent results in terms of chemical efficiency and stereoselectivity of the reactions were obtained; surprisingly, the nature of the protective group at the N4 position of (fluoro)cytosine additionally influenced the stereochemical reaction outcome.
