N-[(2S)-4-Chloro-2-(l-menthyloxy)-5-oxo-2,5-dihydrofuran-3-yl]-l-valine
The title compound, C(19)H(30)ClNO(5), was obtained by the tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)-one and l-valine in the presence of potassium hydroxide. The furan-one unit is approximately planar (r.m.s. deviation = 0.0204 Å) and the six-membered cyclo-hexane ring adopts a chair conformation. The crystal structure is stabilize...

The title compound, C(17)H(26)ClNO(5), was prepared via a tandem asymmetric Michael addition-elimination reaction of (5S)-3,4-dichloro-5-(l-menth-yloxy)furan-2(5H)--one and l-alanine in the presence of potassium hydroxide. The five-membered furan-one ring is approximately planar while the six-membered menth-yloxy ring adopts a chair conformation. The crystal packing is stabilized by inter-molec...

The title compound, C(19)H(30)BrNO(5), was obtained via a tandem asymmetric Michael addition-elimination reaction of 3,4-dibromo-5-[(S)-l-menth-yloxy]furan-2(5H)-one and l-valine in the presence of potassium hydroxide. The mol-ecular structure contains an approximately planar (r.m.s. deviation = 0.0204 Å) five-membered furan-one ring and a six-membered menth-yloxy ring adopting a chair conforma...

In the title compound, C(15)H(12)BrN(3)O(2)S, the dihedral angle between the pyridine and benzene rings is 73.17 (19)°. The five-membered 1,3-thia-zolidine ring has an envelope conformation, with the S atom displaced by 0.196 (1) Å from the mean plane of the four other ring atoms. An intra-molecular C-H⋯N inter-action occurs. The crystal structure is stabil-ized by inter-molecular N-H⋯O and C-H...

In the title compound, C24H17Cl2N3O3, the quinazolinone ring system is close to planar (r.m.s. deviation = 0.0132 Å), with the imide unit almost perpendicular to it, subtending a dihedral angle of 89.1 (1)°. However, the imide unit itself is not planar, the dihedral angle between the two O=C-N components being 34.6 (1)°. The dihedral angle between the two chlorobenzene rings is 40.50 (7)°, whil...
