Abstract
A method of preparing a 2'-fluoro compound of the formula ##STR1## where B is selected from the group consisting of purines and pyrimidines, both of which may be substituted, comprises reacting a compound of the formula II(a) or II(b) ##STR2## where R and R' are as defined in the specification with an acid halide under conditions effective to obtain a halide of the formula ##STR3## where X is a halogen. A silane of the formula B-Si (R').sub.3 where R' is as defined in the specification, is added to this product (III) under conditions effective to obtain a compound of the formula (IV) ##STR4## The compound of formula (IV) is reacted with a reagent selected from the group consisting of ammonia, BCl.sub.3 and ((C.sub.1 -C.sub.10)alkyl).sub.4 NF, under conditions effective to obtain the compound of formula (I). The compounds of formula (I) resulting from these methods exhibit anti-HIV activities and are useful for therapy against the HIV virus.
