Stereocontrolled Total Synthesis of Alkaloid G via the Oxy-anion Cope Rearrangement and Improved Total Synthesis of (+)-Ajmaline

(Matrix Presented) The oxy-anion Cope rearrangement followed by protonation of the enolate which resulted under conditions of kinetic control has been employed to generate the key asymmetric centers at C(15), C(16), and C(20) in alkaloid G (1) and (+)-ajm

Enantiospecific total synthesis of (-)-(E)16-epiaffinisine, (+)-(E)16-epinormacusine B, and (+)-dehydro-16-epiaffinisine as well as the stereocontrolled total synthesis of alkaloid G

An efficient strategy is described for the total synthesis of the sarpagine-related indole alkaloids (-)-(E)16-epiaffinisine (1), (+)-(E)16-epinormacusine B (2), and (+)-dehydro-16-epiaffinisine (4). A key step employed the chemospecific and regiospecific
