Amine-Catalyzed Highly Regioselective and Stereoselective C(sp(2) )-C(sp(2) ) Cross-Coupling of Naphthols with trans-α,β-Unsaturated Aldehydes

Synthesis of 2-arylbenzofuran-3-carbaldehydes via an organocatalytic [3+2] annulation/oxidative aromatization reaction

A novel organocatalytic [3+2] annulation/oxidative aromatization reaction of enals with 2-halophenols is developed for the synthesis of 2-arylbenzofuran-3-carbaldehydes.

Enantioselective organocatalytic Michael addition of isorhodanines to α,β-unsaturated aldehydes

The Michael reaction of substituted isorhodanines with α,β-unsaturated aldehydes in the presence of a catalytic amount of a chiral secondary amine is presented. This transformation proceeds in good to high yields furnishing the corresponding 4,5-disubstituted isorhodanine adducts in good to excellent enantioselectivities.

Stereoselective α-indolylation of enals via an organocatalytic formal cross-coupling with indoles

A novel organocatalytic one-pot cascade bromination–Michael addition dearomatization–nucleophilic rearrangement aromatization cascade process for the direct α-indolylation of unfunctionalized enals from readily available indoles with good yields and high E selectivity has been developed with great simplicity and practicality.
