Nucleoside analogues (+)-4a and (+)-4b were obtained in non-racemic form by a short and efficient way. The key step was a Mitsunobu reaction of alcohol (-)-8 with adenine or protected thymine. The title products were obtained after deprotection steps. (C) 2002 Elsevier Science Ltd. All rights reserved.
