چکیده
The title compound, C(11)H(22)N(2)O(2), has one chiral center and packs in the monoclinic space group P2(1). The asymmetric unit has five crystallographically independent mol-ecules, four of which engage in inter-molecular N-H⋯O hydrogen bonding.

The title compound, C(16)H(22)N(2)O(3), was synthesized during the course of a study on (1R,2S)-norephedrine-derived 1,3,4-oxadiazinan-2-ones. The conformation adopted by the isopropyl group is pseudo-axial relative to the oxadiazinan core. The allylic strain contributes to this conformational arrangement.

The title compound, C(13)H(18)N(2)O(2), is an N(4)-isopropyl-l-phenyl-alanine-based oxadiazinanone. Although the two mol-ecules in the asymmetric unit are oriented appropriately for hydrogen bonding, the distance between the donor and acceptor atoms is large enough to support only weak, if any, hydrogen bonding. The absolute configuration is known based on the known starting compounds in the sy...

The title compound, C(15)H(18)N(2)O(3), is an example of an oxadiazinan-2-one with significant inter-action between the N(3)-acyl and N(4)-methyl groups. These steric inter-actions result in a large torsion angle between the two carbonyl groups, not present with acyl substituents with less steric demand.

The 1,3,4-oxadiazinan-2-one ring in the title compound, C(12)H(13)ClN(2)O(3), is in a distorted half-chair conformation. The phenyl and chloro-acetyl groups occupy axial and equatorial positions, respectively, and lie to the opposite side of the mol-ecule to the N-bound methyl substituent. Mol-ecules are consolidated in the crystal structure by C-H⋯O inter-actions.

The 1,3,4-oxadiazinane ring in the title compound, C(18)H(18)N(2)O(4), is in a twisted boat conformation. The two carbonyl groups are orientated towards the same side of the mol-ecule. The dihedral angle between the planes of the benzene rings is 76.6 (3)°. Mol-ecules are sustained in the three-dimensional structure by a combination of C-H⋯O, C-H⋯π and π-π [shortest centroid-centroid distance =...
