Australine and related alkaloids: easy structural confirmation by C-13 NMR spectral data and biological activities

Abstract:

The first polyhydroxylated pyrrolizidine alkaloid with a hydroxymethyl group at C-3 was isolated from pods of Alexa leiopetala (Leguminosae) and designated alexine 1. The Australian legume Castanospermum australe is also known to produce the same structural type of pyrrolizidines. There are reports of the isolation of australine (7a-epi-alexine) 2, 1-epi-australine 3, 3-epi-australine 4, and 7-epi-australine 5 from this plant to date. Their unambiguous syntheses established that the natural p...
