Transition metal-catalyzed direct C–H bond functionalization enabled by transient ligands has become an attractive topic. Here we report a palladium-catalyzed site-selective arylation of β-C(sp3)–H bonds in aliphatic ketones with β-alanine as the transient ligand.

)-H Bond via Tandem 1,5-HAT and Difunctionalization of Aryl Alkenes
A visible‐lightmediated γ‐hydroxyalkylation of ketones via C(sp3)‐H functionalization has been developed under redox neutral conditions. This protocol relies on the iminyl radical‐triggered 1,5‐HAT followed by oxyalkylation of alkenes, wherein C−C and C−O bonds were constructed in one step. This three‐component reaction features mild conditions, wide substrate scope and excellent functional group

indene pharmacophore and show a high degree of correlationbetween potency of PDI inhibition and bortezomib (Btz) potentiation in MM cells. Inhibition of PDI leads to ER and oxidative stress characterized by the accumulation of misfolded poly-ubiquitinated proteins and the induction of UPR biomarkers ATF4, CHOP, and Nrf2. This work characterizes the synthesis and SAR of a new chemical class and further
copper(II) salts and Dess–Martin periodinane via radical intermediates, as evidenced by TEMPO spin‐trapping experiments. This new method of radical generation is compatible with functionalization and CC bond formation through Giese‐type addition reactions (see scheme; DMSO=dimethyl sulfoxide, TEMPO=2,2,6,6‐tetramethyl‐1‐piperidinyloxyl, free radical).
