چکیده
There are two mol-ecules in the asymmetric unit of the title compound, C(17)H(20)O(4)S(2). There are slight differences in the twist of the two rings relative to the S-C-S chain [dihedral angles of 48.41 (18) and 87.58 (16)° in the first mol-ecule and 45.98 (18) and 87.02 (18)° in the second] and the difference in the C-S-C-S torsion angles [176.68 (17) and -77.6 (2)° for the two independent mol-ecules].

In the title compound, C(21)H(26)N(2)O(3), the morpholine ring has a chair conformation and the dihedral angle between the two phenyl rings is 59.0 (3)°. The crystal packing is stabilized by inter-molecular O-H⋯O hydrogen bonds, generating a ribbon structure along the a axis. An intra-molecular N-H⋯O contact is also present.

The title compound, C(14)H(19)NO(3), was obtained as one of the two isomers of a Sharpless asymmetric dihydroxy-lation reaction of (1S)-1-[(1R)-1-phenyl-ethyl]-4-vinyl-pyrrolidin-2-one. The absolute stereochemistry of this isomer was determined from the known stereochemistry (R) at the bridge C atom between the phenyl and pyrrolidine rings. The mol-ecules form one-dimensional tapes along the b ...

The title compound, C(19)H(27)NO(3), was obtained by the reaction of (3S,7aR)-7a-hexyl-7-meth-oxy-3-phenyl-2,3-dihydro-pyrrolo[2,1-b]oxazol-5(7aH)-one and triethyl-silane using titanium(IV) chloride as catalyst. In the mol-ecule, the phenyl and dihydro-pyrrolone rings form a dihedral angle of 83.8 (1)°. O-H⋯O hydrogen-bonding inter-actions lead to the formation of a chain parallel to the a axis.
