https://www.selleckchem.com/products/sovleplenib-hmpl-523.html We report an Umpolung strategy of enol ethers to generate oxy-allyl cation equivalents based on the use of hypervalent iodine reagents. Under mild basic conditions, the addition of nucleophiles to aryloxy-substituted vinylbenziodoxolone (VBX) reagents, easily available in two steps from silyl alkynes, resulted in the stereoselective formation of substituted aryl enol ethers. The reaction was most efficient with phenols as nucleophiles, but preliminary results were also achieved for C- and N- nucleophiles. In absence of external nucleophiles, the 2-iodobenzoate group of the reagent was transferred. The obtained aryl enol ethers could then be transformed into α-difunctionalized ketones by oxidation. The described "allyl cation"-like reactivity contrast with the well-established "vinyl-cation" behavior of alkenyl iodonium salts.Background Increasing numbers of children with complex health-care needs are cared for at home by their family. The aim of this qualitative study was to explore the challenges experienced by families caring for children who need complex medical care at home. Methods We conducted a thematic analysis of eleven in-depth interviews with parents who carry out specialist medical procedures (eg, enteral feeding, bowel washouts and tracheostomy care) for their children at home. Participants were purposely selected from an existing sample of interviews with parents whose child had abdominal surgery in the first year of life. Results We identified three overarching themes (a) responsibilities of the parent, (b) impact on daily life and (c) the parent journey over time. Parents have substantial responsibilities, including performing medical procedures, managing emergencies (sometimes life-threatening), co-ordinating care and advocating for their child. Their responsibilities have an enormous impact on the family going out of the home becomes a challenge, there are constant constraints on time,
