(4R,5S)-5-Benzyl-4-isopropyl-1,3,4-oxadiazinan-2-one
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(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(20)H(32)ClNO(3), was obtained via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)-one and 4-methyl-piperidine in the presence of potassium fluoride. The furan-one ring is approximately planar [maximum atomic deviation = 0.022 (2) Å] while the cyclo-hexane ring adopts a chair conformation. Weak inter-molecular C-H⋯...

The title compound, C(20)H(30)ClNO(3), was obtained via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)-2(5H)-furan-one and diallyl-amine in the presence of potassium fluoride. The mol-ecular structure contains an approximately planar five-membered furan-one ring [maximum atomic deviation = 0.0221 (3) Å] and a six-membered ring adopting a chair c...
