Abstract: A formal total synthesis of (+ )-madindoline A and (+ )-madindoline B, highly selective inhibitors of interleukin-6, has been accomplished in 11 steps with an overall yield of 8.3% from hexanoic acid. The allene ether version of the Nazarov cyc1ization was used to form the cyclopentenone core of the madindolines. The quaternary carbon center was generated from a ZnBr2-catalyzed condensation reaction between silyl enol ether 2.24 and thioether 2.50.
