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
