(Chemical Equation Presented) The Et3N-assisted addition of benzenethiol to enones in chloroform is catalyzed with high turnover efficiency by the phenyl-substituted uranyl-salophen compound 3. Catalytic data show a close adherence to a quaterm

5,5,Dimethyl-3-phenoxy-2-cyclohexenone (Ib) was reduced with lithium aluminum hydride (LAH) to give the 1,2-addition product (IIIa). 2-Methyl-3-phenoxy-2-cyclopentetnone (IIa) gave a mixture of the allyl alcohol (IVa) and 1,2-addition product (IVb).On the

Asymmetric induction in the Michael reaction has been achieved using alkaloidonium salts in a two-phase system with optical yields of up to 36 and 26percent in the addition to αβ-unsaturated ketones of thiols and nitroalkanes respectively.The presence of a hydroxy-group β to the 'onium function is essential to achieve substantial asymmetric syntheses.
