Polyurethane oligomers from 1,4-butanediol (BD) and toluene diisocyanate (TDI) with a various excess of BD were synthesized. Their molar masses were measured by gel permeation chromatography and the molar mass distribution correlated with the statistic theory. 'H-, 13C-, 'H-'H-COSY-, ATP-, and "N-NM

## Abstract A modified benzyloxycarbonyl (BOC) protective group, the 3,5βdiβ__tert__βbutyl substituted BOC (3,5βtBBOC) group, was introduced to the stepwise synthesis of molecularly uniform oligourethanes based on 1,5βnaphthalene diisocyanate (NDI) and 1,4βbutanediol (BDO) for the protection of the
Synthesis and Properties of 2-Substituted 4-Hydroxy-4-isoxazoline-3ones. -The synthesis of hitherto not described 2-substituted 4-hydroxyisoxazolinones (IV) via intramolecular cyclization of generally unstable bromopyruvohydroxamic acids (III) is accomplished. The novel heterocycles display moderat
