Synthesis of ergot alkaloids from tryptophan

The first total syntheses of lysergine and setoclavine are described, as well as a new and efficient synthesis of lysergic acid. The starting material for these syntheses is tryptophan, protected as its dihydro, dibenzoyl derivative. This material is dehy
