Asymmetric Total Synthesis of (+)-Fusarisetin A via the Intramolecular Pauson–Khand Reaction

An asymmetic total synthesis of (+)-fusarisetin A has been achieved. The essential to our strategy was the application of the intramolecular Pauson–Khand reaction for the stereoselective construction of the trans-decalin subunit of (+)-fusarisetin A with a unique C16 quarternary chiral center. The developed chemistry offers an alternative to the IMDA reaction that has been used for fusarisetin A, and is applicable to analogue synthesis for biological evaluation.
