Crystal structure of (±)-(5SR,6SR)-6-ethenyl-1-[(RS)-1-phenyl-eth-oxy]-1-aza-spiro-[4.5]decan-2-one.

ABSTRACT: In the title compound, C19H25NO2, the pyrrolidine ring adopts an envelope form, with the spiro C atom as the flap, while the cyclo-hexane ring shows a chair form. A weak intra-molecular C-H?O inter-action supports the mol-ecular conformation, generating an S(6) ring motif. In the crystal, pairs of C-H?O inter-actions connect the mol-ecules into inversion dimers with an R 2 (2)(16) ring motif. The dimers are linked by a second pair of C-H?O inter-actions, enclosing an R 4 (2)(12) ring motif, into a tape structure along the b axis.

Project description:In the title compound, C(21)H(23)NOS, the thia-zolidine ring adopts a twist conformation about one of its C-S bonds, while the cyclo-hexane ring has a chair conformation. The S and N atoms attached to the spiro C atom are in axial and equatorial orientations, respectively. The thia-zolidine ring forms dihedral angles of 86.24?(14) and 31.82?(15)° with the directly attached and remote terminal benzene rings, respectively. The dihedral angle between the two terminal benzene rings is 86.74?(14)°. In the crystal, the only significant directional inter-action is a weak C-H?? bond, which generates [010] chains.

Project description:Mol-ecules of the title spiro-[4.5]decane derivative, C(17)H(30)N(2)O(3)S, are linked by paired O-H?N hydrogen bonds into centrosymmetric R(2) (2)(16) dimers and these dimers are linked into a three-dimensional framework structure by C-H?O interactions.

4-(Pyrimidin-2-yl)-1-thia-4-aza-spiro-[4.5]decan-3-one.

Project description:The title compound, C(12)H(15)N(3)OS, features an envelope conformation for the 1,3-thia-zolidin-4-one ring with the S atom as the flap atom. The pyrimidine ring is almost orthogonal to the 1,3-thia-zolidin-4-one ring as indicated by the N-C-C-N torsion angle of -111.96?(18)°. Supra-molecular dimers are formed in the crystal structure through the agency of C-H?O contacts occurring between centrosymmetrically related mol-ecules. These are linked into supra-molecular tapes along [100] via C-H?S contacts.

Project description:In the title compound, C(15)H(26)N(2)O(2)S, the cyclo-hexane and morpholine rings adopt chair conformations, while the thia-zole ring has a twist conformation. An intra-molecular C-H?S hydrogen-bond inter-action forms a five-membered ring. The crystal packing involves C-H?O=C inter-molecular inter-actions where carbonyl O atoms act as double acceptors to two symmetrically related H atoms.

rac-2-Hydroxy-2,8-dimethyl-4-morpho-linoethyl-1-thia-4-aza-spiro-[4.5]decan-3-one.

Project description:The title compound, C(16)H(28)N(2)O(3)S, is dimerized by inversion symmetry-related inter-molecular O-H?N hydrogen bonding, forming an R(2) (2)(16) motif. The dimers are also linked through inter-molecular C-H?O hydrogen bonding. The compound is chiral with a stereogenic centre located in the thia-zole ring, but in the crystal structure it forms a racemate. The thia-zole ring has an envelope conformation, while the cyclo-hexane and morpholine rings adopt chair conformations.

Crystal structures of two chiral piperidine derivatives: 1-[(1R)-2-hy-droxy-1-phenyl-eth-yl]piperidin-4-one and 8-[(1S)-1-phenyl-eth-yl]-1,4-dioxa-8-aza-spiro-[4.5]decane-7-thione.

Project description:The crystal structures of the two title piperidine derivatives show different conformations for the six-membered heterocycle. The N-substituted 4-piperidinone 1-[(1R)-2-hy-droxy-1-phenyl-eth-yl]piperidin-4-one, C13H17NO2, (I), has a chair conformation, while the piperidine substituted in position 2 with a thio-carbonyl group, 8-[(1S)-1-phenyl-eth-yl]-1,4-dioxa-8-aza-spiro-[4.5]decane-7-thione, C15H19NO2S, (II), features a half-chair conformation. Comparison of the two structures, and data retrieved from the literature, suggests that the conformational flexibility is mainly related to the hybridization state of the C atom ? to the piperidinic N atom: a Csp (3) atom favours the chair conformer, while a Csp (2) atom distorts the ring towards a half-chair conformer. In the crystal structure of (I), weak C-H?O hydrogen bonds link the mol-ecules into supra-molecular chains propagating along the b-axis direction. In the crystal of (II), the mol-ecules are linked by weak C-H?S contacts into supra-molecular chains propagating along the b-axis direction.
