To determine the safety and tolerability of 3 doses of intranasal oxytocin (Syntocinon; Novartis, Bern, Switzerland) administered to patients with frontotemporal dementia (FTD). We conducted a randomized, parallel-group, double-blind, placebo-controlled study using a dose-escalation design to test 3 clinically feasible

New classes of thia/oxa-azaspiro[3.4]octanes are synthesized through the implementation of robust and step-economic routes. The targeted spirocycles have been designed to act as novel, multifunctional, and structurally diverse modules for drug discovery. Furthermore, enantioselective approaches to the spirocycles are reported.
