In the crystal structure of the racemic title isoxazolidine, C(19)H(27)NO, the relative stereochemistry between the phenyl group and the bridgehead H atom is shown to be syn. There are two mol-ecules in the asymmetric unit, one of which is the 7R*,13R* enanti-omer, and one of which is the 7S*,13S* enanti-omer. These enanti-omers adopt different orientations of the phenyl ring with respect to the isoxazolidine ring, with C-C-C-C torsion angles of 63.6 (4) and 86.8 (4)°, respectively. In both enan ...[more]
