- Bioinspired total synthesis of montanine-type amaryllidaceae alkaloids
-
Finding a common path: A synthetic strategy inspired by the proposed biogenesis of the montanine-type alkaloids enabled the concise asymmetric synthesis of these compounds in a divergent fashion on the basis of an unprecedented tandem oxidative dearomatization/intramolecular aza-Michael addition as the key step. This bioinspired approach revealed a chemical connection between the cherylline- and montanine-type alkaloids (see scheme). Copyright
