Applications of vinylogous Mannich reactions. Total syntheses of the Ergot alkaloids rugulovasines A and B and setoclavine

Concise syntheses of the Ergot alkaloids rugulovasine A (3a), rugulovasine B (3b), and setoclavine (2) have been completed by strategies that feature inter- and intramolecular vinylogous Mannich reactions as the key steps. Thus, the first synthesis of 3a,
