The SN2 reaction exhibits the classic Walden inversion, indicative of the stereospecific backside attack of the nucleophile on the stereogenic center. Observation of the inversion of the stereocenter provides evidence for an SN2-type displacement. Ho

Diarylprolinol silyl ethers are among the most utilized stereoselective organocatalysts for the construction of complex molecules. With their debut in 2005, these catalysts have been applied in numerous method developments primarily leveraging enamin

A novel strategy for the direct enantioselective oxidative homocoupling of α-branched aldehydes is presented. The methodology employs open-shell intermediates for the construction of chiral 1,4-dialdehydes by forming a carbon–carbon bond connectin

Nucleophile–nucleophile coupling is a challenging transformation in organic chemistry. Herein we present a novel umpolung strategy for α-functionalization of aldehydes with nucleophiles. The strategy uses organocatalytic enamine activation and qui

A new reactivity in organocatalysis is proposed to account for the coupling of carboxylic acids to α-branched aldehydes by combining primary amine catalysis and an oxidant. The developed methodology is an enantioselective α-coupling of aromatic and

An aryl anion is produced by rapid addition of iodide to the p-benzyne diradical formed by cycloaromatization of an enediyne. The aryl anion is then hydronated (protonated or deuteronated) to form 1-iodotetrahydronaphthalene. Hydrons can be incorpora

Enediynes undergo cycloaromatization to p-benzyne diradicals. A new reaction of p-benzynes is here presented. Instead of their usual radical reactivity, they add nucleophiles, followed by protonation. Kinetic evidence showed that the rate-limiting st
