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

Enantiospecific Total Synthesis of the Sarpagine Related Indole Alkaloids Talpinine and Talcarpine as Well as the Improved Total Synthesis of Alstonerine and Anhydromacrosalhine-methine via the Asymmetric Pictet-Spengler Reaction

The enantiospecific total synthesis of talpinine 1 and talcarpine 2 has been accomplished from D-(+)-tryptophan in 13 steps (11 reaction vessels) in 10% and 9.5% overall yields, respectively. Moreover, this synthetic approach has been employed for the improved synthesis of alstonerine 3 and anhydromacrosalhine-methine 4 in 12% and 14% overall yield, respectively. A convenient synthetic route for the enantiospecific, stereospecific preparation of the key intermediate (-)-Na-H, Nb-benzyl tetracyclic ketone 15a via the asymmetric Pictet-Spengler reaction on a multihundredgram scale has been developed. A diastereocontrolled (>30:1) anionic oxy-Cope rearrangement and the intramolecular rearrangement to form ring-E and an Nb-benzyl/Nb-methyl transfer reaction also served as key steps. This general approach can now be utilized for the synthesis of macroline/ sarpagine related indole alkaloids and their antipodes for biological screening.

The enantiospecific total synthesis of norsuaveoline

Norsuaveoline la has been synthesized enantiospecifically in 28% overall yield from commercially available D-(+)-tryptophan methyl ester via the asymmetric Pictet-Spengler reaction and a stereocontrolled oxy-anion Cope rearrangement as key steps.
