Summary Until recently, the direct oxidative oxysulfonylation of carbonyl compounds was limited to ketones. Here, we report the first direct oxytriflation of simple, non-activated amides. Amide umpolung with triflic anhydride and pyridine-N-oxide in

The catalytic asymmetric carbometalation of cyclopropenes followed by either an electrophilic oxidation or amination reaction provides a unique approach to the formation of diastereomerically pure and enantiomerically enriched cyclopropanol and cyclo

The distant functionalization of ω-ene cyclopropanols is induced by a Pd-catalyzed Heck reaction triggering a "metal-walk" and selective ring-opening of the three-membered ring. This approach provides a new class of acyclic aldehydes possessing conc
