Abstract
The (7R,8R) stereochemistry of naturally occurring 7 beta-angelyl-1-me thylene-8 alpha-pyrrolizidine 5 was confirmed by subjecting a mixture of a synthetic standard and the natural product to various chiral diff erentiating techniques. The synthetic 7 beta-angelyl-1-methylene-8 alp ha-pyrrolizidine 1 was prepared from enantiomerically pure retronecine 3.
