Synthesis, resolution, and absolute configuration of novel tricyclic benzodiazepines
摘要:
The synthesis, resolution, and stereochemical characterization of novel piperazino-, thiazino-, and oxazinoberizodiazepines are described. The absolute stereochemistry of the heterotricycles was determined by using X-ray crystallography and the enantiomeric purity was determined by using Pirkle-solvent NMR techniques and chiral HPLC.
