As scientists closely watch avian influenza A (H5N1) or "bird flu" as a potential progenitor of an influenza pandemic, researchers from the Department of Health and Human Services, Centers for Disease Control and Prevention, and Oak Ridge Institute for Science and Education conducted with focus groups with the public and interviews with healthcare providers(More)
The strategy considered herein features an iodocyclofunctionalization/hydrogen-transfer reaction sequence for the elaboration of propionate motifs. Proceeding with excellent yield and diastereoselectivity, the synthetic sequence proposed gives access to the anti-anti dipropionate motif when the reduction step is performed under the control of the exocyclic(More)
[reaction: see text] A tandem process featuring intramolecular aminyl radical cyclofunctionalization and hydrogen transfer affords 2,3-trans-disubstituted pyrrolidines with anti or syn diastereoselectivity. The extension of this strategy to iminyl radicals gives trans-anti pyrrolenines with high levels of 1,2-induction in both steps of the tandem process.
Reported herein is a strategy employing a Mukaiyama reaction in tandem with a hydrogen transfer reaction for the elaboration of propionate motifs. The nature of the protecting groups on the chiral beta-alkoxy aldehyde and the type of Lewis acid used are varied to modulate the stereochemical outcome of the tandem reactions. The mode of complexation is thus(More)
