Iodosulfonation of alkenes with benzenesulfinic acid - N-iodosuccinimide - Facile preparation of αβ-unsaturated sulfones
Wolff, Russell R.,Basava, Vikram,Giuliano, Robert M.,Boyko, Walter J.,Schauble, J. Herman
, 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
Stereoselective synthesis of trans-4,5-disubstituted oxazolidin-2-ones by intramolecular conjugate addition of N-p-toluenesulfonyl carbamates
Ciclosi, Marco,Fava, Cristiana,Galeazzi, Roberta,Orena, Mario,Sepúlveda-Arques, José,González-Rosende, Maria Eugenia
, p. 1173 - 1183 (2007/10/03)
p-Toluenesulfonyl carbamates (2a-d) were prepared starting from allylic alcohols (3), in which the double bond is conjugated with an electron withdrawing group. In the presence of a catalytic amount of DBU, an intramolecular cyclisation occurred, leading
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%).
Facile synthesis of E-γ-hydroxy-α,β-unsaturated sulfones from aldehydes
Dominguez,Carretero
, p. 2487 - 2490 (2007/10/02)
Reaction of enolizable aldehydes with p-tolylsulfinylmethyl phenyl sulfone (1), in the presence of piperidine in acetonitrile at 0°C, gave selectively E-γ-hydroxy-α,β-unsaturated phenyl sulfones in good yields.
