S-Phenyl 4-methoxybenzothioate
In the mol-ecule of the title thio-ester, C(14)H(12)O(2)S, the dihedral angle between the phenyl and benzene rings is 71.8 (3)°. The meth-oxy group is essentially coplanar with the benezene ring to which it is bonded, with an r.m.s. deviation of 0.0065 (5) Å for the non-H atoms involved. In the crystal, weak C-H⋯π inter-actions are present.
متن کاملS-Phenyl benzothioate
In the title compound, C(13)H(10)OS, the phenyl rings are inclined to one another by 51.12 (8)°. There is a short C-H⋯S contact in the molecule.In the crystal, molecules are linked via C-H⋯O hydrogen bonds forming chains along the a axis. Molecules are also linked by C-H⋯π and weak π-π interactions [centroid-centroid distance = 3.9543 (10) Å].
متن کاملThe enantioselective synthesis of (S)-(+)-mianserin and (S)-(+)-epinastine
A simple enantioselective synthetic procedure for the preparation of mianserin and epinastine in optically pure form is described. The key step in the synthetic pathway is the asymmetric reduction of the cyclic imine using asymmetric transfer hydrogenation conditions.

The asymmetric unit of the title compound, C(10)H(15)NOS, contains two independent mol-ecules with similar conformations. In the crystal, mol-ecules are linked in a head-to-tail fashion by N-H⋯O hydrogen bonds into chains running along the b axis. The absolute configuration was assigned on the basis of known chirality of the parent compound.
متن کامل(S)-6-Methyl-∊-caprolactone
The chiral title compound, C(7)H(12)O(2), a lactone derivative, features a seven-membered ring that adopts a chair conformation. The crystal structure is stabilized by weak C-H⋯O inter-actions occurring in the (100) plane. The absolute configuration was assigned on the basis of the enantioselective synthesis.
