Triplet Energy Transfer‐Driven Intermolecular [2+2] Photocycloaddition of Acyclic Imines and Indoles: Facile Access to Azetidine‐Fused Indolines

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
An intermolecular aza‐Paternò‐Büchi reaction of indoles and acyclic imines is enabled by visible‐light‐driven triplet energy transfer, providing azetidine‐fused indolines up to 93% yield for 30 examples and providing a novel protocol to access previously inaccessible scaffolds. ABSTRACT Currently, successful examples of the aza‐[2+2] photocycloaddition

Penicillin allergy de‐labelling in the critical care unit: Simulations to design an intravenous drug provocation test that mirrors the plasma profile of an enteral challenge

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 3, Page 997-1002, March 2026.
The majority of penicillin allergy labels are incorrect and a label of penicillin allergy is associated with worse outcomes and increased use of healthcare services. Penicillin allergy assessment and de‐labelling may be considered in critically ill patients. An oral penicillin challenge is a common component of most penicillin allergy protocols.

Amitriptyline Induced Life‐Threatening Steven–Johnson Syndrome: Case Report

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Stevens–Johnson syndrome is one of the few dermatological emergencies in clinical practice. The syndrome is often secondary to the usage of drugs, of which allopurinol, penicillins, sulfa drugs, ibuprofen, sodium valproate, phenytoin, lamotrigine, and carbamazepine are commonly implicated.

A Case Series of Hypermucoid Klebsiella pneumoniae Liver Abscess in Caucasian Americans Without Travel History: An Epidemiologic Shift?

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) is an emerging cause of community‐acquired pyogenic liver abscess (PLA), classically described in East and Southeast Asia. We report two cases of hvKp‐associated PLA in Caucasian women of American origin with no history of international travel, animal exposure, or Asian food consumption. Both patients

Divergent Access to Spirocyclic and Atropisomeric Benzimidazothiazole Derivatives by Halogen‐Promoted Intramolecular Dienamine Sulfenylation

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
A divergent halogen‐promoted intramolecular sulfenylation of dienamines enables access to two unprecedented families of benzo[4,5]imidazo[2,1‐b]thiazole. The resulting scaffolds feature distinct chiral elements, either a quaternary stereocenter in the case of spirolactones, or a stereogenic axis for heteroaryl‐alkenes, with high configurational ...
