A concise synthetic route to the conduritols from pentoses
Keinicke, Lise,Madsen, Robert
, p. 4124 - 4128 (2005)
A short synthetic strategy for preparation of the conduritols is described. The key step employs a zinc-mediated fragmentation of protected methyl 5-deoxy-5-iodo-D-pentofuranosides followed by an allylation of the intermediate aldehyde in the same pot. Th
