Nucleophilic, Ferrocenium-Catalyzed Ring-Opening Reactions of Propargylic Alcohols with Unactivated Cyclopropyl Substituents to Afford Enynes: Trends and Selectivity

Inorganics
Ferrocenium-catalyzed transformations provide a practical and sustainable approach to propargylic substitution reactions. Herein, we investigate the ring-opening of cyclopropyl-substituted propargylic alcohols with alcohol nucleophiles, catalyzed by ...

Novel stereocontrolled syntheses of tashiromine and epitashiromine

Beilstein Journal of Organic Chemistry, 2015
A novel stereocontrolled approach has been developed for the syntheses of tashiromine and epitashiromine alkaloids from cyclooctene β-amino acids. The synthetic concept is based on the azetidinone opening of a bicyclic β-lactam, followed by oxidative ...

The Radical Ring-Opening Polymerization of Cyclic Ketene Acetals Revisited: An Experimental and Theoretical Study [PDF]

, 2020
Radical Ring-Opening polymerization (rROP) of Cyclic Ketene Acetals (CKAs) combines the advantages of both ring-opening and radical polymerization thereby allowing the robust production of polyesters.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Cationic-anionic synchronous ring-opening polymerization

Nature Communications
Chemical reactions with incompatible mechanisms (such as nucleophilic reactions and electrophilic reactions, cationic polymerization and anionic polymerization) are usually difficult to perform simultaneously in one-pot.

Safety of Daprodustat for the Treatment of Chronic Kidney Disease Anemia: Final Analysis of a Multicenter Postmarketing Surveillance Study in Japan

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This final analysis of a multicenter, prospective postmarketing surveillance study evaluated the safety of daprodustat in patients with chronic kidney disease anemia in routine clinical practice in Japan. Methods Patients who initiated daprodustat between September 2020 and July 2022 were registered.

Ring-Opening Metathesis of a Cyclic Imine

, 2016
Pyrroline, a five-membered cyclic imine, undergoes ring-opening metathesis with alkylidene complexes of the class Mo(CHR‘)(NAr)(OR)2 (Ar = 2,6 diisopropylphenyl; R = CMe3, CMe2(CF3), CMe(CF3)2; R‘ = CMe3, CPhMe2).

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Ring-Opening Olefin Metathesis of Twisted Amides: Activation of Amide Bonds by CC Cleavage

, 2019
Selective CC bond cleavage in twisted amides by ring-opening olefin metathesis (ROM) was accomplished. The reaction represents the third mechanism for ring opening of nonplanar amide bonds discovered.

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.
