Abstract

A new subgroup of the Amaryllidaceae alkaloids having a 10b,4a-ethanoiminodibenzo[b, d] pyrane (2-benzopyrano[3,4-d]indole) nucleus is isolated from two different Galanthus species as three novel monomeric alkaloids, (+)-graciline (1), (+)-11-acetoxygraciline (2) and (+)-3,4-dihydro-3-hydroxygraciline (3). The fourth new compound, (-)-digracine (4) is a dimer of two such moieties.
