Two new alkaloids, norpandamarilactonine-A (1) and -B (2), which have a pyr
rolidinyl-alpha,beta -unsaturated gamma -lactone moiety as in the known pan
damarilactonine alkaloids, were isolated from the leaves of Pandanus amaryl
lifolius. Their structures were determined by spectroscopic analysis and to
tal synthesis.
