Reaction of α-amino carbonyl compounds with SmI2 in THFâHMPA in the presence of a proton source afforded the deamination products, where the fragmentation occurred between the nitrogen and the carbon α to the carbonyl group.
A formal total synthesis of securinine (1) was achieved by employing an intramolecular Diels–Alder reaction of the enol ester, derived from 2-acetylpyridine and sorbic anhydride, as a key step.
The present disclosure is generally directed to antiviral compounds, and more specifically directed to compounds which can inhibit the function of the NS5A protein encoded by Hepatitis C virus (HCV), compositions comprising such compounds, and methods for inhibiting the function of the NS5A protein.
An intramolecular Diels-Alder reaction of the enol ester derived from 2-acetylpyridine and sorbic anhydride gave the cycloaddition product, stereoselectively, which was further converted into the key intermediate for the synthesis of securinine.
