Abstract

The enantiomeric synthesis of L-cyclopentenyl nucleosides is described. The key intermediate (+)-cyclopentenyl alcohol (8) was prepared from methyl-alpha-D-galactopyranoside 1 using a ring closing metathesis reaction. Transformation of the allylic alcohol 8 into the allylic acetate (9) or carbonate (10), allows their coupling with purine and pyrimidine bases under Pd(0)-catalyzed Tsuji-Trost allylic alkylation's to yield 12a-c. The Pd catalyzed reaction was found to require the use of AlEt3. (C) 2004 Elsevier Ltd. All rights reserved.
