Synthesis of 2′,3′-modified carbocyclic L -nucleoside analogues
Jessel, Soenke,Meier, Chris
experimental part, p. 1702 - 1713 (2011/05/04)
New divergent approaches to 2′,3′-modified carbocyclic L-nucleoside analogues starting from enantiomerically pure (1R,2S)- or (1S,2R)-2-(benzyloxymethyl)cyclopent-3-enol are described. In the key step, stereochemically pure cyclopentanols were condensed with N3-protected thymine through a modified Mitsunobu protocol. Moreover, several routes to different cyclopentanol derivatives, to prepare carbocyclic L-2′,3′-didehydro- 2′,3′-dideoxynucleosides (L-d4N), L-2′,3′- dideoxynucleosides (L-ddN), and L-ribonucleosides are reported.

A Novel, One-Pot Ring Expansion of Cyclobutanones. Syntheses of Carbovir and Aristeromycin

, p. 1865 - 1872 (2007/10/03)
A novel, one-pot ring-expansion procedure was developed using Me3S(O)I, NaH, and Sc(OTf)3. The scope and limitations were briefly examined, and a tentative mechanism was proposed. Application of the methodology to known cyclobutanone 1 provided the corresponding cyclopentanone, which was successfully advanced to (+)-carbovir and (+)-aristeromycin.
