title: Capture-ROMP-release: application for the synthesis of O-alkylhydroxylamines.
abstract: [reaction: see text] A new capture-ROMP-release method for chromatography-free purification of N-hydroxysuccinimde Mitsunobu reactions is described. The Mitsunobu reaction captures a variety of alcohols onto a norbornenyl N-hydroxysuccinimide monomer. Subjection of the resulting crude reaction mixture to ROM-polymerization generates a polymer that can be precipitated with methanol and filtered from the Mitsunobu byproducts. Treatment of the polymer with hydrazine releases the substrate from the water-soluble polymer, producing a variety of O-alkylhydroxylamines with good purity.
