Asymmetric 1,3-dipolarcycloadditions of chiral carboxyloyl nitrile oxidesderivedfrom (2R)-bornane-10,2-sultam, (1R)-8-phenylmenthol, N,N-dicyclohexyl-10-sulfamoyl-(2R)-isoborneol, and 7,7-dimethylnorbornane-(1S,2R)-oxazolidinone to four cycloalkenes, leading to the corresponding 2-isoxazolines in both moderate yields and diastereoselectivities, are presented. All cycloadducts were converted into
