Article Abstract
A new metal-free oxidative radical [2+2+1] carbocyclization of benzene-linked 1,n-enynes with two C(sp(3))-H bonds adjacent to the same heteroatom is described. This method achieves two C(sp(3))-H oxidative functionalizations and an annulation, thus providing efficient and general access to a variety of fused five-membered carbocyclic hydrocarbons.

Thioesterification of Polyfluoroarenes via Copper-Catalyzed Radical Cross-Coupling with KS and Aldehydes in Water.
Org Lett

College of Materials and Chemical Engineering, Key Laboratory of Inorganic Nonmetallic Crystalline and Energy Conversion Materials, China Three Gorges University, Yichang, Hubei 443002, P. R. China.
A novel copper-catalyzed radical cross-coupling reaction for the thioesterification of polyfluoroarenes is developed using KS and aldehydes in water. This protocol employs a readily available KS as a sulfur source, eliminating the need for hazardous thiols and organic solvents. The mild reaction conditions are compatible with a wide range of functional groups, providing access to diverse polyfluoroaryl thioesters.

Purpose: We aimed to evaluate the impact of day- and night-time pad wetness on 2yrs-QoL after Radical Cystectomy (RC) with Orthotopic Neobladder (ON) from a Randomized Controlled Trial (RCT) aimed at comparing open RC (ORC) and Robot-Assisted RC (RARC) with intracorporeal (i) ON.
Methods: Between January 2018 and September 2020, 116 patients were enrolled. Data from self-assessed questionnaires (EORTC-QLQ-C30 and QLQ-BLM30) were collected.
CT-Based Radiomics Models with External Validation for Prediction of Recurrence and Disease-Specific Mortality After Radical Surgery of Colorectal Liver Metastases.

Purpose: To build computed tomography (CT)-based radiomics models, with independent external validation, to predict recurrence and disease-specific mortality in patients with colorectal liver metastases (CRLM) who underwent liver resection.
Methods: 113 patients were included in this retrospective study: the internal training cohort comprised 66 patients, while the external validation cohort comprised 47. All patients underwent a CT study before surgery.
Tetrahydroxydiboron-mediated radical cyclization of unactivated alkenes toward ring-fused quinazolinones.

A tetrahydroxydiboron-mediated radical cyclization of unactivated alkenes under photoinduced reaction conditions was developed to synthesize ring-fused quinazolinones for the first time. The concise, mild and photocatalyst- and oxidant-free conditions, as well as the good functional group tolerance, render this protocol a green and convenient strategy for synthesizing polycyclic ring-fused quinazolinones. Mechanistic studies indicated that the process might involve a radical pathway.
