Silylation of bicyclic six-membered nitronates was studied as a possible route to conjugated enoximes with a distant carbonyl group. Apart from the target enoximes, this reaction yielded nitro compounds. The ratio of these two types of products and the co
Reversed Stereochemical Course of the Michael Addition of Cyclohexanone to β-nitrostyrenes by Using 1-(Trimethylsiloxy)cyclohexene/Dichloro(diisopropoxy)titanium

Induced by a stoichiometric excess of dichloro(diisopropoxy)titanium, 1-(trimethylsiloxy)cyclohexene and p-substituted β-nitrostyrenes (Y=H, CH3, CH3O, CN) combine in CH2Cl2 solution at -90 deg preferentially with relative topicity ul - opposite to the co
