The dynamic kinetic resolution of C–N atropisomeric pyridones was achieved via asymmetric phase-transfer catalysis, exploiting a rotational barrier-lowering hydrogen bond in the starting materials. X-ray and NMR experiments revealed the presence of

Nature's oligomeric macromolecules have been a long-standing source of inspiration for chemists producing foldamers. Natural systems are frequently conformationally stabilised by macrocyclisation, yet this approach has been rarely adopted in the fiel

Inspired by naturally occurring molecules containing atropisomeric N + ‐C axes, we have developed a novel synthetic approach to generate a library of axially chiral N ‐aryl quinolinium salts. Enantiopurities up to 93% ee were obtained via a four

Optical sensing offers a low‐cost and effective means to sense carbon monoxide in air and in solution. This contribution reports the synthesis of a new series of vinyl complexes [Ru(CH=CHR)Cl(CO)(TBTD)(PPh3)2] (R = aryl, TBTD = 5‐(3‐thienyl)‐
The EPSRC are thanked for funding PD and JAF in the very early stages of this work (EP/M003868/1). Catalyst-controlled regioselectivity in palladium-catalyzed carbonylation of alkenes has been a long-standing goal of homogeneous catalysis. In general
