carboxylic acid ester. Preliminary assays indicate that illudinine and several related synthetic analogues are monoamineoxidase inhibitors, which is the first reported indication of biological activity associated with this natural product. Illudinine was found to inhibit monoamineoxidase B (MAO-B) with an IC50 of 18 ± 7.1 μM in preliminary assays.

[GRAPHICS]Rapid and efficient [2 + 2 + 2] cyclotrimerization reactions were discovered through the application of microwave irradiation in conjunction with a Ni(CO)(2)(PPh3)(2) catalyst. This enables the facile construction of highly substituted indane, isoindoline, and tetraline core structures. The developed microwave-mediated Ni-catalyzed cyclotrimerization reaction was employed as the key step in a concise synthesis of the isoquinoline natural product illudinine. This represents the first example of a Ni-catalyzed cyclotrimerization reaction in total synthesis.

A total synthesis of the illudalane sesquiterpene illudinine was realized in eight steps and 14% overall yield from commercially available dimedone. The approach features tandem fragmentation/Knoevenagel-type condensation and microwave-assisted oxidative cycloisomerization to establish the isoquinoline core. Completion of the synthesis involves a recently reported cascade SNAr/Lossen rearrangement
