Regiospecific, Enantiospecific Total Synthesis of the Alkoxy-Substituted Indole Bases, 16-epi-Na-Methylgardneral, 11-Methoxyaffinisine, and 11-Methoxymacroline as Well as the Indole Alkaloids Alstophylline and Macralstonine
TL;DR: The key C-19 ketosarpagine system (borane adducts) employed for the construction of 11-methoxymacroline was also transformed into alstophylline 25, which resulted in completion of the total synthesis of the bisindole macralstonine.
