Abstract

Abstract NEW MATERIAL: The (S)-isomer of a compd. of formula I (where OH in the chain may be in the form of its o-acyl, phosphate, cyclic acetal or cyclic carbonate deriv.) or a mixture of the (S)-isomer with <45 wt.% of the corresponding (R)-isomer. EXAMPLE: (S)-2-amino-9-(2,3-dihydroxyprop-1-oxy)purine. USE: A viral infection treating agent. PROCESS: The (S)-isomer of the compd. of the formula I is obtd. by reducing a compd. of formula II (where each of R a and R b is H or a protective group) and optionally converting R a and/or R b into OH or optionally forming a deriv. and/or a salt of the resultant compd.
