Abstract
Synthesis of 2,3-Dihydro-1H-pyrrolizine-7-carbaldehyde, the Sex Pheromone Danaidal Danaidal (4) can easily be obtained in high yields from ethyl 2,3,5,6-tetrahydro-1H-pyrrolizine-7-carboxylate (1) via sulphur dehydrogenation or MnO2 oxidation, subsequent reduction to dehydrosupinidine (3), and further oxidation to the desired title compound 4.
