Crossed products: Ortho‐substituted benzaldehydes react with other aromaticaldehydes in a highly selective, atom‐economical Tishchenko disproportionation (see scheme) in the presence of a readily prepared, inexpensive thiolate‐based catalyst. The methodology is of exceptionally wide scope and exhibits a high functional‐group tolerance.

Biaryl atropisomers are of great importance in natural products, pharmaceuticals, and asymmteric synthesis. The efficient synthesis of these chiral scaffolds with full enantiocontrol and high diversity remains challenging. Reported herein is a Pd‐catalyzed atroposelective C−H allylation with tert‐leucine as an efficient catalytic chiral transient auxiliary. A wide range of enantioenriched biaryl aldehydes

We report the discovery of benzoxaborole antitrypanosomal agents and their structure activity relationships on central linkage groups and different substitution patterns in the sulfur-linked series. The compounds showed in vitro growth inhibition IC(50) values as low as 0.02 mu g/mL and in vivo efficacy in acute murine infection models against nryapnosoma brucei.

catalyzed by a bis-cyclometalated rhodium catalyst in the presence of visible light. Mechanistic experiments and DFT calculations support a mechanism in which a photoexcited catalyst/substrate complex triggers an intramolecular hydrogen-atom transfer followed by a highly stereocontrolled hetero-Diels-Alder reaction. In this reaction scheme, the rhodium catalyst fulfills multiple functions by 1) enabling
