Journal ArticleDOI

A general and selective zinc-catalyzed oxidation of sulfides to sulfoxides

TL;DR: A general zinc-catalyzed oxidation of sulfides to sulfoxides has been developed in this article, where hydrogen peroxide was used as a green oxidant to achieve moderate to excellent yields.
Journal ArticleDOI

Asymmetric Supramolecular Catalysis: A Bio-Inspired Tool for the High Asymmetric Induction in the Enamine-Based Michael Reactions

TL;DR: Enantiomerically pure, druglike hexahydroxanthenes with three contiguous stereocenters were synthesized through supramolecular catalysis by D-proline and quinine-NH-thiourea followed by reductive etherification from simple precursors under mild conditions.
Journal ArticleDOI

Efficient synthesis of 2-imino-1,2-dihydroquinolines and 2-imino-thiochromenes via copper-catalyzed domino reaction

TL;DR: In this paper, a one-pot approach to 2-imino-1,2-dihydroquinolines and 2-IMino-thiochromenes from sulfonyl azides, alkynes, and 2acyl anilines or the potassium salt of 2mercapto-benzaldehyde has been developed.
Journal ArticleDOI

Organocatalytic Asymmetric Formation of Steroids

TL;DR: A novel and simple one-step approach for the construction of optically active steroids in a highly stereoselective manner by using organocatalysis is presented, which allows an easy access to opticallyactive steroids with a variety of substituents in the A ring in high yields and up to greater than 99 % ee.

Synthesis and structure of a hexacoordinate carbon compound.

TL;DR: In an exploration of six coordination and hypervalence in carbon compounds, steric constraints have been employed to bring four ether O atoms in close proximity to an allenic carbon atom.
