(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.
متن کامل5-Isopropyl-5-methyl-2-sulfanylideneimidazolidin-4-one
In the title compound, C7H12N2OS, the 2-sulfanylideneimidazolidin-4-one moiety is nearly planar, with a maximum deviation of 0.054 (2) Å. In the crystal, a pair of N-H⋯O hydrogen bonds and a pair of N-H⋯S hydrogen bonds each form a centrosymmetric ring with an R 2 (2)(8) graph-set motif. The enanti-omeric R and S mol-ecules are alternately linked into a tape along [1-10] via these pairs of hydr...
متن کامل(4S)-Benzyl 4-isopropyl-5-oxo-1,3-oxazolidine-3-carboxylate
In the crystal structure of the title compound, C(14)H(17)NO(4), obtained by the reaction of N-benzoxycarbonyl-l-valine, paraformaldehyde and 4-methyl-benzene-sulfonic acid, mol-ecules are linked by C-H⋯O hydrogen bonds, generating linear chains parallel to the a axis. C-H⋯π inter-actions of stacked benzene rings also provide stability for the crystal structure.
