In general, for methylene bridged BOX ligands the stereochemical outcome is consistent with a twisted square planar intermediate that was proposed based on related crystal structures. The substituent at the oxazoline's 4-position blocks one enantiotopic face of the substrate, leading to enantioselectivity. This is demonstrated in the following aldol-type reaction, but is applicable to a wide v…
WebAbstract Polymers based on 2-oxazoline, such as poly (2-ethyl-2-oxazolines) (PETOx), are considered to be a type of 'pseudopeptide' with the ability to form novel biomaterials. The hydrolysis of PETOx was carried out to evaluate its use in biomedical applications. Web2-Ethyl-2-oxazoline (EtOx) is an oxazoline which is used particularly as a monomer for the cationic ring-opening polymerization to poly (2-alkyloxazoline)s. [2] This type of polymers are under investigation as readily water-soluble and biocompatible materials for biomedical applications. [3] Production [ edit]
WebThey are the saturated analogues of bisoxazolines . They are used as performance modifiers in polyurethane coatings and paints. The rings hydrolyze in the presence of moisture to give amine and hydroxyl groups, which can then react with diisocyanates, polyisocyanates and polyurethane prepolymers to form a coating. WebAbstract The synthesis of linear polyethylenimine (L-PEI) is mostly performed via the acidic or basic hydrolysis of poly (2-alkyl-2-oxazoline)s (PAOx). Besides full hydrolysis …
