α-Alkylated (dimethylsilyl)acetonitriles (Me2HSiCR 3R4CN) react spontaneously with aldehydes in DMSO to give β-hydroxynitriles in good to high yields. The addition to ketones is effectively promoted by using MgCl2/su

Rhodium to the rescue: The formal aldol products of carboxamides (CONH 2) were obtained by using a RhI(OR) (R=H, Me) catalyst under essentially neutral pH and ambient conditions. This novel aldol strategy is based on the catalytic al

We report an innovative approach for the selective synthesis of polyfunctional derivatives by cross-combination of different radicals generated under mild conditions. The coordinating effect of Ti(IV) plays a key role in the reaction mechanism: due to its chelating action on the hydroxyl groups, it promotes the homolytic C-C bond cleavage of α,β-dihydroxy ketones by enhancing the captodative effect and the consequent stabilization of the corresponding α-hydroxy-α-carbonyl radicals. When these radicals are generated in the presence of stoichiometric amounts of TiCl4 and 2,2'-azo-bis-isobutyronitrile (AIBN) is employed as a source of α-cyanoisopropyl radicals, the selective radical-radical cross-coupling is observed, affording the corresponding β-hydroxynitriles in high yields. This innovative methodology allows application of the well-known Ingold-Fischer effect to a wider range of stabilized carbon-centered radicals, whose formation derives from the chelating action of Ti(IV).
