Short and Scalable Total Synthesis of Myrioneuron Alkaloids (±)-α,β-Myrifabral A and B.

The first total synthesis of the Myrioneuron alkaloids (±)-α,β-myrifabral A and B has been accomplished in only four steps from conveniently available starting materials. This short synthesis relied on the use of a key tandem Mannich/amidation reaction to rapidly construct the core framework and two carbon stereocenters. The synthetic route allows for large scale preparation of these promising natural products against the hepatitis C virus (HCV).
