Resolution of racemic cis-6-chloro-9-[2-(hydroxymethyl)cyclopentyl]-9H-purine 1 was performed using HPLC with a semipreparative column of beta -cyclodextrin using 85:15 water/acetonitrile as eluent. The absolute configurations of the were determined by NMR studies of their (R)- and (S)-methoxyphenylacetates. (C) 2001 Elsevier Science Ltd. All rights reserved.
