2 ALEXINES [3-HYDROXYMETHYL-1,2,7-TRIHYDROXYPYRROLIZIDINES] FROM CASTANOSPERMUM-AUSTRALE
Two new alexines have been isolated from Castanospermum australe. The structure of 1,7a-diepialexine was firmly established by X-ray crystallographic analysis of the corresponding 1,7-isopropylidene derivative. The structure of the second new alexine was tentatively assigned as 7,7a-diepialexine or...
