Novel three synthetic routes to (±)-6,7-secoagroclavine were developed from either methyl 3-(3-formylindol-4-yl)acrylate, indole-4-carbaldehyde, or 4-iodoindole-3-carbaldehyde. The total syntheses of (±)-chanoclavine-I, (±)-chanoclavine-II, and (±)-agroclavine-I were accomplished as well from the synthetic intermediates involved in the synthesis of (±)-6,7-secoagroclavine, culminating in establishing an efficient and common synthetic method for ergot alkaloids.

The simple total synthesis of the ergot alkaloids, (+/-)-norchanoclavine-I, (+/-)-chanoclavine-I, (+/-)-isochanoclavine-I, and (+/-)-agroclavine was achieved by a practical and common synthesis method.A new regio-selective oxidation of the Z-methyl group of the isoprenyl system with selenium dioxide is described.Keywords - (+/-)-norchanoclavine-I; (+/-)-norisochanoclavine-I; (+/-)-chanoclavine-I; (+/-)-isochanoclavine-I; (+/-)-agroclavine; ergot alkaloid; total synthesis; common synthesis method; new oxidation
