Stereodivergent route to the carbocyclic core of 2',3'-olefinic carbanucleosides: toward the synthesis of (L)-(+)- and (D)-(-)-carbovir.

Abstract

(R)-2,3-Cyclohexylideneglyceraldehyde (1) has been elegantly exploited for a stereodivergent construction of the potential precursors (11a and 11b) of (L)-(+)- and (D)-(-)-carbovirs, respectively. The key steps in this approach were Luche's allylation of formaldehyde with allylic bromide 4c to produce 5 and ring-closing metathesis of 10b using Grubbs' first… (More)
