A Facile Access to Antiflu Agent Tamiflu/OseltamivirSynlett 2009; 2009(17): 2884-2884
DOI: 10.1055/s-0029-1218288

Abstract

A practical approach to Tamiflu is developed featuring the construction of the carbocycle core of the target molecule through a Diels-Alder reaction with concurrent introduction of one of the nitrogen atoms. Incorporation of another nitrogen atom was achieved via a high-yielding regioselective ring opening of a cyclic sulfite.

Key words

Diels-Alder reactions - eliminations - enantiomeric ­resolution - epoxides - antiviral agents
