Pharmacological considerations promted the authors to synthesize a series of 8-hydroxylated optically active derivatives of diazabicyclononanes and of their 2,5-dioxo analogs from trans-4-hydroxy-L-proline.Esterification with appropriate anhydrides led to the corresponding esters with 6S,8R configuration.Inversion of configuration at C-8 was performed using Mitsunobu method and led to the diastereoisomeric series of 6S,8S esters.A tentative pharmacological evaluation was carried out in the area of sedative and spasmolytic activities.
