(R)-2,3-Di-O-benzylglyceraldehyde and N-tosyl homoallylamine undergo aza-Prins cyclization to afford (1R,5S,7S)-7-[(benzyloxy)methyl]-2-tosyl-6-oxa-2-azabicyclo[3.2.1]octane in a highly diastereoselective manner through an unexpected intramolecular nucleophilic attack. Our work has opened a new route toward the asymmetric synthesis of 7-(alkyl or aryl)-6-oxa-2-azabicyclo[3.2.1]octane derivatives from chiral α-hydroxyaldehyde derivatives in one step.

Synthesis of the AB ring segments of ciguatoxin is described. The present synthesis includes a Lewis acid mediated cyclization of allylstannane with aldehyde, cross-metathesis reaction introducing the side chain, and Grieco-Nishizawa dehydration on the A ring.

, p. 49 - 54 (2008/02/08)
The total synthesis of natural (-)-pramanicin, a highly oxygenated γlactam-type antifungal agent, is described. The enantiospecific total synthesis of this natural product commenced with 5-deoxy-1,2-O-isopropylidene-α-d-xylofuranose as an enantiopure star
