We present a tandem aza-Heck/Suzuki cross-coupling reaction of -phenyl hydroxamic ethers with readily available arylboronic and alkenyl boronic acids. This protocol is enabled by a palladium catalyst paired with chiral phosphoramidite ligands, particularly under mild reaction conditions, yielding efficient and succinct synthetic routes to chiral isoindolinones with high enantioselectivity. Furthermore, this reaction exhibits excellent functional group compatibility and a rich diversity of subsequent transformations.

Although methods for synthesizing chiral phosphorus scaffolds are available, the potential of this molecular chirality remains largely unexplored. Herein, we present a remote desymmetrization of prochiral biaryl phosphine oxides through an organocatalytic asymmetric arylation. This metal-free approach enables the efficient synthesis of a wide range of densely functionalized P(V)-stereogenic compounds with good to excellent yields and satisfactory enantioselectivities.

Importance: Drug-coated balloon (DCB) angioplasty has emerged as an alternative to drug-eluting stent (DES) implantation for percutaneous coronary intervention (PCI) in patients with coronary in-stent restenosis (ISR) as well as de novo coronary artery disease.
Observations: DCBs are balloons coated with antiproliferative agents and excipients, whose aim is to foster favorable vessel healing after appropriate lesion preparation. By providing homogeneous antiproliferative drug delivery in the absence of permanent foreign body implantation, DCBs offer multiple advantages over DES, including preservation of vessel anatomy and function and positive vessel remodeling.

Seven different enzymes comprise the galactosyltransferases family, of which β-1,4-galactosyltransferase I (β-1,4-GALT1) is the major contributor to galactosylation activity in cells. Since abnormalities in galactosylation are associated with many pathophysiological conditions, β-1,4-GALT1 is an interesting new target for drug discovery and molecular probe design. There are several known β-1,4-GALT1 inhibitors, but most of them suffer from low cell permeability and thus low in vivo activity.

Importance: Women are underrepresented in leadership positions in cardiology. Institutional grand rounds (GR) are platforms through which faculty can gain professional exposure and access to career development opportunities. The gender diversity of invited cardiology GR speakers has not been investigated.
