(8'aR)-2',3',8',8'a-Tetrahydro-5',6'-dimethoxyspiro[2,5-cyclohexadiene-1,7'(1'H)-cyclopenta[ij]isoquinoline]-4-one Usage And Synthesis
DescriptionA spiroisoquinoline alkaloid from Stephania glabra, the base has [α]26D + 143° (c 1.88, CHCI3). It contains two methoxyl groups and an imino group and yields a crystalline N-acetyl derivative, m.p. 234-5°C; [α]24D- 80° (c 1.57, CHCI3). The N-methyl compound has been shown to be identical with Pronuciferine (q.v.).
