  日期：2011.8

  Polyfuncionalized cyclopentanones with three contiguous stereogenic centers were formed in good to excellent yields and stereoselectivities by utilizing a secondary amine/N-heterocyclic carbene catalytic system in the reaction of β-oxo sulfones with unsaturated aldehydes. In addition, the influence of the catalysts on the diastereoselectivity of the final product was studied by 1H NMR spectroscopy

  A straightforward synthesis of virtually unexplored terminally disubstituted electron-deficient alkylidene cyclopent-2-en-4-ones was elaborated using activated secondary sulfones as alkylidene anion-radical synthons. The presented olefination process is proposed to rely on a base-promoted tandem or sequential Michael addition of C-nucleophiles to 4-acyl- or 4-silyloxycyclopent-2-en-1-ones followed
