Abstract

A new alkaloid (1) containing an indolizidine ring, named tashiromine, was isolated from the stems of Maackia tashiroi (Leguminosae) together with seven lupin alkaloids and ammodendrine. The structure of 1 was determined as (5S,6R)-5-hydroxymethyl-trans-indolizidine or its enantiomer by comparison of the spectral data with those of the synthetic diastereomers of 5-hydoxymethyl-trans-indolizidine. © 1990.
