(Z)-N-{3-[(2-Chloro-1,3-thia-zol-5-yl)meth-yl]-1,3-thia-zolidin-2-yl-idene}cyanamide.

In the title compound, C(8)H(7)ClN(4)S(2), the thia-zole ring is essentially planar [r.m.s.

Crystal structure of a new cyclomaltoheptaose hydrate: beta-cyclodextrin.7.5H2O.

The crystallographic study of a partially hydrated form of cyclomaltoheptaose (beta-cyclodextrin, betaCD) is reported. C(42)H(70)O(35).7.

2-Isopropyl-3-methyl-quinoxaline 1,4-dioxide.

In the title compound, C(12)H(14)N(2)O(2), the quinoxaline ring system and the C atoms of the methylene and methyl substituents lie on a mirror plane. The crystal packing is stabilized by weak π-π inter-actions [centroid-centroid distance = 3.680 (7) Å].

N-(Ferrocenylmethyl)-dodecan-1-amine.

The title compound, [Fe(C(5)H(5))(C(18)H(32)N)], was synthesized by the amination of ferrocenecarbaldehyde. In the complex, the two cyclo-penta-dienyl (Cp) rings are almost parallel with a dihedral angle of 1.36 (8)°, and are separated by a centroid-centroid distance of 3.

New cyclodextrin derivative 6-O-(2-hydroxybutyl)-beta-cyclodextrin: preparation and its application in molecular binding and recognition.

A new soluble cyclodextrin derivative 6-O-(2-hydroxybutyl)-beta-cyclodextrin (6-HB-beta-CD) was prepared. Its molecular binding and recognition ability were investigated with the comparison of beta-cyclodextrin (beta-CD), 2-O-(2-hydroxypropyl)-beta-cyclodextrin (2-HP-beta-CD), 6-O-(2-hydroxypropyl)-beta-cyclodextrin (6-HP-beta-CD), and 2-O-(2-hydroxybutyl)-beta-cyclodextrin (2-HB-beta-CD). The relationship between the complex stability constants and the possible structures of inclusion compounds was discussed with the interaction of hosts and guests, including the weak hydrophobic interactions, the size/shape matching, the steric hindrance, and the hydrophilic property.

New cyclomaltoheptaose (beta-cyclodextrin) derivative 2-O-(2-hydroxybutyl)cyclomaltoheptaose: preparation and its application for the separation of enantiomers of drugs by capillary electrophoresis.

A new soluble cyclomaltoheptaose (cyclodextrin) derivative, 2-O-(2-hydroxybutyl)cyclomaltoheptaose [2-O-(2-hydroxybutyl)-beta-cyclodextrin, 2-HB-beta-CD], was prepared and studied as an efficient chiral selector in the separation of racemic mixtures of drugs by capillary electrophoresis (CE). Results showed that 2-HB-beta-CD could provide higher separating capability than that of beta-CD and the similarly substituted 2-HP-beta-CD.
