Abstract

Die beiden parallelen Alkenoyleinheiten des abgebildeten cyclischen Dithiolans ermöglichen eine [7C+1C] ‐ Anellierung mit Isocyanessigsäureethylester. Somit sind tricyclische Indolizidin ‐ Alkaloide in zwei Stufen durch basekatalysierte [7C+1C] ‐ Anellierung/intramolekulare Cyclisierung mit anschließender Reduktion/Cyclisierung zugänglich.
