Visible-Light-Driven Stereoselective Annulation of Alkyl Anilines and Dibenzoylethylenes via Electron Donor-Acceptor Complexes

A catalyst-free, stereoselective visible-light-driven annulation reaction between alkenes and N,N-substituted dialkyl anilines for the synthesis of substituted tetrahydroquinolines is presented. The reaction is driven by the photoexcitation of an electron donor-acceptor (EDA) complex, and the resulting products are obtained in good to high yields with complete diastereoselectivity. Mechanistic rationale and photochemical characterization of the EDA-complex are provided.

An Expedient, Direct, Three-Component Approach for the Synthesis of 4-Thioarylpyrroles

A three-component strategy for the synthesis of 4-thioarylpyrroles from 1,4-enediones, thiols, and ammonium formate in one-pot has been developed. The reaction proceeds through the sequential thiol-Michael/Paal-Knorr reaction of 1,4-enediones with the for

Asymmetric diastereoselective synthesis of spirocyclopropane derivatives of oxindole

A new asymmetric organocatalytic synthesis of spirocyclopropane oxindoles has been developed. The method is based on the Michael addition of N-Boc-protected 3-chlorooxindole to unsaturated 1,4-dicarbonyl compounds, affording trans-substituted spirocyclopropane oxindole derivatives in high diastereo- and enantioselectivity.
