Origins of regio- and stereoselectivity in additions of phenylselenenyl chloride to allylic alcohols and the applicability of these additions to a simple 1,3-enone transposition sequence
The invention is directed to [1,2,4]thiadiazine 1,1-dioxide compounds and pharmaceutical compositions containing such compounds that are useful in treating infections by hepatitis C virus.

3-Alkoxycarbonyl-2-ethoxy-2-propenylidenetriphenylphosphorane reacts in turn with alkyl halides and aldehydes in the presence of base via a one-pot procedure to give moderate to good yields of conjugated enol ethers. Hydrolysis of the conjugated enol ethers and subsequent decarboxylation provide a novel route to α,β-unsaturated ketones.

Dithianes and dithiolanes at benzylic or allylic carbons can easily be hydrolyzed by IBX in DMSO, whereas non-activated dithianes/dithiolanes are much more stable under these conditions. (C) 2002 Elsevier Science Ltd. All rights reserved.
