The (7R,8R) stereochemistry of naturally occurring 7β-angelyl-1-methylene-8α-pyrrolizidine 1 was confirmed by subjecting a mixture of a synthetic standard and the natural product to various chiral differentiating techniques. The synthetic 7β-angelyl-1-methylene-8α-pyrrolizidine 1 was prepared from enantiomerically pure retronecine 3.
