Abstract Whereas the conventional anti-dihalogenation of alkenes is a valuable synthetic tool with highly predictable stereospecificity, the restricted reaction mechanism makes it challenging to alter the diastereochemical course into the complementa

Thiirane, the sulfur congener of oxirane, has been hard to access in a stereodefined form. Here, the authors accomplished a highly stereoselective synthesis of cis-diarylthiiranes through the stereospecific sulfurization of E,E-aldazine N-oxides.

Ultrafast intramolecular proton transfers of 1,2-dihydroxyanthraquinone (alizarin-h2) and its deuterated product (alizarin-d2) in dimethyl sulfoxide (DMSO) have been investigated by femtosecond stimulated Raman spectroscopy. The population dynamics i

Our group has recently developed an α-fluoroamine synthesis using dioxaphospholenes derived from various 1,2-diketones and the dealkylation-resistant phosphoramidite as carbene surrogates, enabling the formal insertion into the N–F bond of (PhSO2)

The synthesis of α-fluoroamines was achieved via deoxygenative geminal fluorosulfonimidation of 1,2-diketones using a dealkylation-resistant phosphoramidite under mild conditions that require neither excess reagents nor transition metal catalysts.

A convenient, pyridine-boryl radical-mediated pinacol coupling of diaryl ketones is developed. In contrast to the conventional pinacol coupling that requires sensitive reducing metal, the current method employs a stable diboron reagent and pyridine L
