Abstract

The synthesis of two macrocyclic fragments in the manadomanzamine alkaloids based on a strategy using reductive nucleophilic addition to macrolactams is reported. The sequence through the Wittig coupling and macrolactamization gives quick access to both eleven-membered and ten-membered macrolactams. The iridium-catalyzed reductive Strecker reaction of the ten-membered macrolactam takes place via the corresponding unstable imine intermediate.
