An efficient iodine-mediated oxidation of tetrahydro-β-carbolines is described to yield aromatic β-carboline products with tandem CâH oxidation. The utility of the method was demonstrated in total syntheses of the alkaloids eudistomins Y1âY7.

The first total synthesis of eudistomin Y7 (7) and totalsyntheses of eudistomins Y1–Y6 (1–6) are described. An efficient room-temperature conversion of 1-benzyl-3,4-dihydro-β-carbolines (11) into 1-benzoyl-β-carbolines (14) by a one-potprocess of tandembenzylicoxidation and aromatization as the key step of these totalsyntheses was also studied in detail.
