simple and effective Pd(II)-catalyzed regioselectiveC(2)–H arylation of 6,5-fused heterocycles with dioxazolones as a masked ester surrogate undermildconditions is reported. The significance of the arylation is highlighted by the new reactivity demonstrated in dioxazolones via proximal C–H activation of the cyclic carbonate of the hydroxamic acid functionalityunder protic conditions.

We report an enantio- and diastereoselective, complete hydrogenation of multiply substituted benzofurans in a one-pot cascade catalysis. The developed protocol facilitates the controlled installation of up to six new defined stereocenters and produces architecturally complex octahydrobenzofurans, prevalent in many bioactive molecules. A unique match of a chiral homogeneous ruthenium-N-heterocyclic

A copper(II) acetate/(R)‐DTBM‐SEGPHOS‐catalyzed ring opening of benzofurans and enantioselective hydroamination cascade with dimethoxymethylsilane (DMMS) and hydroxylamine esters is described. Starting from readily available substituted benzofurans, a series of chiral N,N‐dibenzylaminophenols, which are of high interest in pharmaceutical chemistry, were obtained with excellent enantioselectivities (up
