摘要

We described herein the optimization of the synthetic methodology exploited to obtain the pyrazolo [3, 4-b] pyrrolo [3, 4-d] pyridine sedative prototype 1a and novel analogues designed by successive molecular simplifications. By applying microwave irradiation during the hetero Diels-Alder key-step to obtain the heterotricyclic scaffold, under solvent-free conditions, we were able to obtain the desired compounds in drastically shorter times and ...
