Application of palladium (O)-catalyzed processes to the synthesis of oxazole-containing partial ergot alkaloids

Syntheses of the potent 5-HT(1A) agonists 2 and 3 were accomplished in several steps from the 6-iodo partial ergoline alkaloid 8. Disparate tactics available for construction of differentially substituted oxazoles led to the development of new and general methodology critical to the efficient preparations of 2 and 3. A novel palladium(O)- and copper(I)-cocatalyzed cyanation reaction provided efficient access to the nitrile 10, a key intermediate in the synthesis of 2. A palladium(O)-catalyzed cross-coupling reaction of 16 with oxazole-2-lyzinc chloride formed the potent 5-HT(1A) agonist 3.

Synthetic studies on LY228729 (3) afforded two innovative approaches for the construction of this class of partial ergoline 5HT(1a) receptor agonists. The first synthesis is based upon a diastereoselective epoxidation of racemic olefin 5, followed by ring
