A catalytic bicyclization reaction of 1,5-enynes anchored by α,β-conjugates with arylsulfonyl radicals generated in situ from sulfonyl hydrazides has been established using TBAI (20 mol%) and Cu(OAc)2 (5 mol%) as co-catalysts under convenient c
Enantioselective sulfonation of enones with sulfonyl imines by cooperative N-heterocyclic-carbene/thiourea/tertiary-amine multicatalysis

supporting information, p. 12354 - 12358 (2013/12/04)
Many hands make light work: In an organocatalytic asymmetric sulfonation of enones, the activation of a sulfonyl imine by an N-heterocyclic carbene (NHC) catalyst led to the release of a sulfinic anion, which underwent nucleophilic addition to the enone. The enantioselectivity of the process was controlled by a chiral thiourea/amine co-catalyst through anion recognition and hydrogen-bonding interactions. Tol=p-tolyl. Copyright
FeCl3ATMSCl: An effective catalytic system for the conjugate addition of sodium p-toluenesulfinate to αβ-enones
Sreedhar,Reddy, M. Amamath,Reddy, P. Surendra
experimental part, p. 1949 - 1952 (2009/04/10)
A new protocol for the β-sulfonation of αβ-unsaturated carbonyl compounds is described. The method employs FeCl3 as catalyst and TMSC1 as additive for conjugate addition of sodiump-toluenesulfinate to enones.
Synthesis, separation and characterisation of diastereomeric mixtures of 3-p-toluenesulfonyl-1,3-diaryl-propan-1-ols
Sayed,Wadia
, p. 362 - 364 (2007/10/03)
Four diastereomeric mixtures of 3-p-toluenesulfonyl-1, 3-diarylpropan-1-ols were prepared by the reduction of the corresponding β-sulfonyl ketones and the stereochemistry of the individual separated (HPLC) diastereomers was established on the basis of PMR data.
KINETIC STUDIES ON THE ADDITION OF p-TOLUENESULFINIC ACID TO BENZYLIDENEACETOPHENONES
Kobayashi, Michio,Miura, Asako
, p. 169 - 173 (2007/10/02)
Kinetics of the addition of p-toluenesulfinic acid to p-substituted benzylideneacetophenones has been investigated.The reaction was second order, first order each in the concentration of sulfinic acid and chalcone.Effects of the p-substituents on the reac
