Transition-metal-catalyzed aromatic C–H functionalization assisted by the phosphorus-containing directing groups

open access: yesGreen Synthesis and Catalysis, 2023
Transition-metal-catalyzed C–H bond functionalization has attracted tremendous attention as an increasingly important protocol for the construction of C–C and C–X bonds.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Rollover Cyclometalation as a Valuable Tool for Regioselective C–H Bond Activation and Functionalization

open access: yesMolecules, 2021
Rollover cyclometalation constitutes a particular case of cyclometallation reaction. This reaction occurs when a chelated heterocyclic ligand loses its bidentate coordination mode and undergoes an internal rotation, after which a remote C–H bond is ...

C-H Functionalization of Commodity Polymers.

open access: yesAngewandte Chemie, 2019
Synthetic manipulation of polymer substrates is one of the oldest and most reliable methods to increase the functional diversity of soft materials. Modifying the chemical structure of polymers that are already produced on a commodity scale leverages the ...

Atroposelective Synthesis of Axially Chiral Styrenes via an Asymmetric C–H Functionalization Strategy

open access: yesChem, 2020
Summary Axially chiral styrenes, which exhibit a chiral axis between a substituted alkene and an aromatic ring, have been largely overlooked. The hurdle is the lower barriers to rotation compared with that of their biaryl counterparts, rendering their ...

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...

Electrophotocatalytic C─H Functionalization of Ethers with High Regioselectivity.

open access: yesJournal of the American Chemical Society, 2020
The highly regioselective electrophotocatalytic C-H functionalization of ethers is described. These reactions are catalyzed by a trisaminocyclopropenium (TAC) ion in a mild electrochemical potential with visible light irradiation.

Early Impact of Childhood Opportunity on Neurocognitive Outcomes in Sickle Cell Disease

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neurocognitive impairment is a well‐recognized complication of sickle cell disease (SCD) that begins early in childhood and persists across development. While cerebrovascular injury contributes substantially to risk, neurocognitive deficits are also observed in children without overt or silent cerebral infarctions, suggesting ...

Cobalt(III)-catalyzed asymmetric ring-opening of 7-oxabenzonorbornadienes via indole C–H functionalization

open access: yesNature Communications, 2023
Asymmetric ring-opening (ARO) reactions, which can help quickly build molecular complexity, have not been extensively shown via β-oxygen elimination. Here, the authors report a cobalt(III)-catalyzed ARO reaction, providing mechanistic insights and the ...
