Oxidative Ring Expansion of Cyclobutanols: Access to Functionalized 1,2-Dioxanes
, 2020 Cyclobutanols undergo an oxidative ring expansion into 1,2-dioxanols by using Co(acac)2 and triplet oxygen (3O2) as radical promoters. The formation of an alkoxy radical drives to the regioselective break of the strained ring with stabilization of a new ...

Ring expansion reactions of P=O-containing molecules [PDF]
, 2023 A series of ring expansion reactions of P=O-containing molecules have been developed for the synthesis of medium-sized ring cyclic phosphonate esters and phosphonamidates. The reactivity trends initially appear to be counter-intuitive, compared with more

The Role of Hematopoietic Cell Transplantation in Ataxia‐Telangiectasia
Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Ataxia‐telangiectasia (A‐T) is a DNA repair disorder characterized by neurodegeneration, immunodeficiency, and cancer predisposition. Hematopoietic cell transplantation (HCT) is an established therapy in related disorders such as Fanconi anemia (FA) and Nijmegen breakage syndrome (NBS), but its role in A‐T is unclear.
