Enantioselective total synthesis of (-)-flustramines A, B and (-)-flustramides A, B via domino olefination/isomerization/Claisen rearrangement sequence.
The concise total synthesis of marine alkaloids, (-)-flustramines A and B, and (-)-flustramides A and B has been achieved through the domino olefination/isomerization/Claisen rearrangement (OIC) for highly enantioselective construction of the asymmetric quaternary carbon center and the chemoselective reduction-cyclization (RC) for pyrrolidine formation as key steps.
