Synthesis of (+)-uniflorine A: A structural reassignment and a configurational assignment

The total synthesis of (+)-uniflorine A has allowed for the structural reassignment and the configurational assignment of the alkaloid (-)-uniflorine A from a 1,2,6,7,8-pentahydroxyindolizidine structure to (-)-(1R,2R,3R,6R,7S,7aR)-1,2,6,7-tetrahydroxy-3-hydroxymethylpyrrolizidine (6-epi-casuarine).
