, p. 667 - 675 (2007/10/03)
Reaction of alkenes and alkenols with N-iodosuccinimide (NIS) and benzenesulfinic acid in dichloromethane at room temperature affords vic-iodophenylsulfonyl adducts in good to high yields. Treatment of the iodosulfones with neutral alumina in dichlorometh
Control of Diastereofacial Selectivity in the Nucleophilic Epoxidation of γ-Oxygenated α,β-Unsaturated Sulfones
Jackson, Richard F. W.,Standen, Stephen P.,Clegg, William
, p. 149 - 156 (2007/10/02)
Epoxidation of γ-oxygenated-α,β-unsaturated sulfones 6-10 with either lithium or potassium tert-butyl peroxide proceeds with moderate to high diastereoselectivity to give mixtures of the syn-2-(phenylsulfonyl)oxiranes 11-15 and the corresponding anti-2-(p
A practical route to (E)-γ-hydroxy-αβ-unsaturated phenyl sulfones
Dominguez, Esteban,Carretero, Juan Carlos
, p. 7197 - 7206 (2007/10/02)
Reaction of enolizable aldehydes with p-tolylsulfinylmethyl phenyl sulfone (1) in the presence of piperidine in acetonitrile gave selectively E-γ-hydroxy-αβ-unsaturated phenyl sulfones (2) in good yields. Reaction from enantiomerically pure sulfoxide 1 gave unsaturated sulfones 2 in moderate optical yields (ee= 10-50%).
