Geometric enantiomerism in cyclic compounds: Chiral dibrominated 1,3‐dioxanes

The first geometric enantiomers in the cyclic compounds series are reported. The investigated compounds are 2,2?disubstituted?5?methyl?1,3?dioxane derivatives in which the substituents at position 2 bear chiral centers with identical substituents but with opposite configurations.

Enantioseparation of benzazoles and benzanilides on polysaccharide-based chiral columns

The chiral recognition ability of the polysaccharide-based chiral columns (Chiralpak AD-RH, Chiralpak AS-RJ, Chiralpak IC, Chiralcel OD-RH, and Chiralcel OJ-RH) for the benzazoles and the benzanilides was evaluated under reversed phase conditions.

Synthesis, Chiral Resolution and Pharmacological Evaluation of a 2,3-Benzodiazepine-Derived Noncompetitive AMPA Receptor Antagonist

2,3-Benzodiazepine derivatives: 1-(4-Aminophenyl)-3,5-dihydro-3-N-ethylcarbamoyl-5-methyl-7,8-methylenedioxy-4H-2,3-benzodiazepin-4-one was synthesized, and its enantiomers were separated by chiral HPLC.
