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.
TOTAL SYNTHESES OF (+/-)-AGROCLAVINE-I, (+/-)-6-NOR-CHANOCLAVINE-II, AND (+/-)-CHANOCLAVINE-II

, p. 895 - 898 (2007/10/02)
The first total syntheses of (+/-)-6-nor-chanoclavine-II and (+/-)-chanoclavine-II are achieved.Total synthesis of (+/-)-agroclavine-I is also reported.
SHORT-STEP SYNTHESIS OF THE ERGOT ALKALOIDS, (+/-)-NORCHANOCLAVINE-I, (+/-)-CHANOCLAVINE-I, (+/-)-ISOCHANOCLAVINE-I, and (+/-)-AGROCLAVINE

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

A preliminary study on the exploitation of a general synthetic route to the ergoline group of alkaloids on the despyrrole analogs was succesfully extended to the first total synthesis of racemic lysergene and agroclavine via the route involving reductive photocyclization of the furylenamide (10) followed by ring opening of the resulting dihydrofuran ring (11).
