A concise synthetic approach toward tamiflu (oseltamivir phosphate): cis-aziridine as the key synthon and RCM†
Abstract
The key synthon cis-aziridine has been efficiently utilised for the synthesis of oseltamivir phosphate, using Wittig olefination, Barbier addition, Mitsunobu reaction and ring closing metathesis (RCM) as key essentials.
