A novel and efficient NHC-catalyzed [3+ 3] annulation of enals with pyrrol-4-ones was
developed, thus providing the dihydropyrano [3, 2-b] pyrrol-5-one core structures with broad …

The isothiourea-catalysed enantioselective Michael addition of 3-aryloxindole and 4-
substituted-dihydropyrazol-3-one pronucleophiles to α, β-unsaturated p-nitrophenyl esters is …

A new general concept for α, β‐unsaturated acyl ammonium catalysis is reported that uses p‐
nitrophenoxide release from an α, β‐unsaturated p‐nitrophenyl ester substrate to facilitate …

A variety of γ-keto-β-silyl esters and amides, most with extremely high enantioselectivities,
were efficiently prepared via a carbene-catalyzed formal [4+ 2] annulation followed by ring …

Herein we report the enantioselective (4+ 2) annulation of donor–acceptor cyclobutanes and
unsaturated acyl fluorides using N‐heterocyclic carbene catalysis. The reaction allows a 3 …
