Depolymerization of methyl pyrrolidinone chitosan by lysozyme

Carbohydrate Polymers, 1992
Abstract Methyl pyrrolidinone chitosan is being tested as a wound dressing material endowed of biological significance. In order to clarify its fate and role when applied to a surgical wound, its hydrolytic depolymerization by hen egg white lysozyme was studied in vitro. Viscometric measurements at three temperatures (25, 37 and 50°C) and five methyl

Intramolecular Radical Amidooxygenation of Alkenes for the Construction of Pyrrolidinones

Organic Letters
An intramolecular 1,2-amidooxygenation of unactivated alkenes for the construction of the pyrrolidinone scaffold containing a masked 5-hydroxymethyl functionality is reported. γ,δ-Unsaturated N-aryloxyamides react with sodium 2,2,6,6-tetramethylpiperidin-1-olate (TEMPONa) to afford alkoxyaminated pyrrolidinones.
