A series of octahydropyrrolo[3,4-c]pyrroles were synthesized and evaluated by orexin 1 and 2 receptor (OX1 & 2R) antagonists assays. Compound 14l with potent OXR antagonist activity and suitable pharmacokinetic behavior was chosen to be investigated in an EEG study, which demonstrated effects of sleep promotion comparable to Suvorexant. Furthermore, the di-fluro substituted analogs exhibited reduced hERG inhibition while maintaining moderate potency.

A highly-efficient catalytic system for hydrodebenzylation reaction is described. The cleavage of O-benzyl and N-benzyl protecting groups was performed using an uncommonly low palladium loading (0.02–0.3 mol%; TON up to 5000) in a relatively short reaction time. The approach was used for a variety of substrates including pharmaceutically important precursors, and gram-scale deprotection reaction was shown. Transfer conditions together with easy-to-make Pd/C catalyst are the key features of this debenzylation scheme. (Figure presented.).

A pyrrolidine compound and its synthetic method, will be dissolved in an organic solvent in the cyclic imide compound with hydrogen as a reducing agent of the reagent and a Lewis acid as a catalyst mixing, under the condition of refluxing to prepare the aromatic ring and fat ring pyrrolidines. Synthetic route of this invention is simple, efficient and economic, mild condition, wide applicability, to pyrrolidines compound at the later stage of industrial production will play a great role in promoting.
