Concise, enantioselective total synthesis of (-)-alstonerine

(Chemical Equation Presented) A novel enantioselective total synthesis of (-)-alstonerine has been completed that requires only 15 steps from L-tryptophan. The synthesis features the first application of a Pauson-Khand reaction to synthesize an azabridged

The first regiospecific, enantiospecific total synthesis of 6-oxoalstophylline and an improved total synthesis of alstonerine and alstophylline as well as the bisindole alkaloid macralstonine

(Chemical Equation Presented) A Wacker sequence has been modified to rapidly generate ring E of (-)-alstonerine, (+)-6-oxoalstophylline, and (-)-alstophylline via a domino process. This one-pot sequence provides facile entry into the dihydropyranyl enone unit of many Alstonia alkaloids.
