Abstract The totalsynthesis of both the double bond isomers of indolizine alkaloid 8-deoxypumiliotoxin 193H has been accomplished. Both the double bond isomers Z-4 and E-4 induced convulsions and inhibited neuro-muscular activity at a dose of 25 mg/kg after intraperitoneal injection in mice. The lethal dose of Z-4 and E-4 was 100 mg/kg, indicating that 8-deoxypumiliotoxin 193H is 10-times less toxic

A stereoselective totalsynthesis of one diastereomer of 8-deoxypumiliotoxin 193H is described. The concise totalsynthesis features the use of readily available natural amino acids as the starting materials and the Ireland–Claisenrearrangement as the key stereochemistry controlling step.
