Dl. Selwood et al., SYNTHESIS AND BIOLOGICAL EVALUATION OF THE L-ENANTIOMER OF 2'-DEOXY-5-ETHYL-4'-THIOURIDINE, Bioorganic & medicinal chemistry letters, 6(8), 1996, pp. 991-994
Racemic 2'-deoxy-5-ethyl-4'-thiouridine was synthesised utilising the
stereoselective iodolactonisation of -butyldimethyIsilyl)oxy-N,N-dimet
hyl-4-pentenamide as the key transformation. The stereo-isomeric mixtu
re of nucleosides was resolved using HPLC on a Chiralcel OJ column. Th
e beta-D enantiomer showed potent activity against human herpesviruses
while the beta-L was inactive. Copyright (C) 1996 Elsevier Science Lt
