چکیده
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.

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 centr...

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.
