Incidence and In‐Hospital Mortality of Ventricular Septal Rupture Following Acute Myocardial Infarction

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Ventricular septal rupture (VSR) is a rare but devastating complication of acute myocardial infarction (MI), associated with high mortality despite advances in reperfusion therapy. However, contemporary data examining national trends in VSR outcomes and the evolving role of mechanical circulatory support (MCS) in this population ...

Twisted 1‐ and 2‐Azaperopyrenes: Synthesis, Structure, and Properties

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT A synthesis of hitherto unknown 1‐ and 2‐azaperopyrenes, twisted nitrogen‐doped peropyrenes, is reported. The synthesis is based on a Brønsted acid‐mediated benzannulation of alkynes. Key alkyne intermediates are synthesized via two complementary routes, including a Pd/C‐catalyzed, copper‐ and amine‐free Sonogashira‐type coupling of (hetero ...

Regio‐ and Diastereoselective C–C Silylation of Cyclopropyl Acetates Harnessing Fluorinated Poly(pyridyl)Borate Rhodium Catalysts

open access: yesChemistry – A European Journal, EarlyView.
Fluorinated poly(pyridyl)borates have been utilized to stabilize rhodium‐diene complexes and as supporting ligands in rhodium‐catalyzed redox‐neutral C–C silylation of cyclopropyl acetates, producing silicon‐containing heterocyclic products, dioxasilolanes.

Pd‐Catalyzed C─C Bond Borylation of Biphenylenes Leading to Tri‐Ortho‐Substituted Biaryls

open access: yesChemistry – A European Journal, EarlyView.
Palladium‐catalyzed ring‐opening C─C borylation of 1‐substituted biphenylenes yields a range of o,o,o′‐trisubstituted biaryls with two ortho‐boryl groups via selective cleavage of the least hindered C─C bond. The resulting diborylated products are readily amenable to sequential, site‐selective postfunctionalization.
