A carbene-catalyzed LUMO activation of α,β-unsaturated alkyne esters is reported. This catalytic process allows for effective reactions of alkyne esters with enamides to synthesize functional pyridines via simple protocols. A previously unexplored unsaturated alkyne acyl azolium intermediate is involved in the key step of the reaction.

N-sulfonyl imines are widely used as substrates for a range of transformations. Access to N-sulfonyl aldimines is straightforward through direct condensation between the parent aldehyde and the sulfonamide. However, this approach is not efficient for the

Raney-Ni/EtOH reduction of different N-sulfonylimines provides a new entry for synthesizing sulfonamides in good yields under mild conditions. This protocol, which does not require additional hydrogen, constitutes a cheap, safe, and easy-to-handle alterna
Asymmetric Strecker reaction of ketoimines catalyzed by a novel chiral bifunctional N,N′-dioxide

, p. 2579 - 2584 (2007/10/03)
A novel bifunctional N,N′-dioxide derived from L-prolinamide was employed to catalyze the enantioselective Strecker reaction of a range of N-tosyl ketoimines, and an effective additive was used to improve the reactivity (up to 99% yield) as well as the en
