A General Pd-Catalyzed C2-H Arylation of Benzoxazoles with Highly Sterically Congested Aryl Chlorides Enabled by a Fittingly Tuned Ligand.

The benzoxazole core, featuring a sterically congested 2,6-disubstituted aryl fragment at the C2 position, exhibits exclusive three-dimensional structures that are essential for particular applications in material science and pharmaceutical development. Despite their importance, the synthesis of these compounds has posed challenges with an efficient preparation strategy still lacking. In this study, we introduced a new indolylphosphine ligand, , specifically designed to facilitate the C2-H arylation of benzoxazoles with sterically hindered aryl chlorides in general.

Metallaphotocatalytic triple couplings for modular synthesis of elaborate N-trifluoroalkyl anilines.

The integration of trifluoromethyl groups and three-dimensional quaternary carbon moieties into organic molecules has emerged as a prominent strategy in medicinal chemistry to augment drug efficacy. Although trifluoromethyl (hetero)aromatic amines and derivatives are prevalent frameworks in pharmaceuticals, the development of trifluoromethyl-embedded, intricately structured alkyl amine scaffolds for medicinal research remains a significant challenge. Herein, we present a metallaphotoredox multicomponent amination strategy employing 3,3,3-trifluoropropene, nitroarenes, tertiary alkylamines, and carboxylic acids.

Symptom-triggered testing detects early stage and low volume resectable advanced stage ovarian cancer.

Objective: Symptom-triggered testing for ovarian cancer was introduced to the UK whereby symptomatic women undergo an ultrasound scan and serum CA125, and are referred to hospital within 2 weeks if these are abnormal. The potential value of symptom-triggered testing in the detection of early-stage disease or low tumor burden remains unclear in women with high grade serous ovarian cancer. In this descriptive study, we report on the International Federation of Gynecology and Obstetrics (FIGO) stage, disease distribution, and complete cytoreduction rates in women presenting via the fast-track pathway and who were diagnosed with high grade serous ovarian cancer.

Investigating harms of testing for ovarian cancer - psychological outcomes and cancer conversion rates in women with symptoms of ovarian cancer: A cohort study embedded in the multicentre ROCkeTS prospective diagnostic study.

Objective: To investigate psychological correlates in women referred with suspected ovarian cancer via the fast-track pathway, explore how anxiety and distress levels change at 12 months post-testing, and report cancer conversion rates by age and referral pathway.

Design: Single-arm prospective cohort study.

Setting: Multicentre.
