Chemical synthesis and alkaloids

A family of novel polyhydroxy-nor-tropanes is described. Three of their structures were determined by mass spectrometry and 1H and 13C NMR spectroscopy. These calystegins occur in two species of the Convolvulaceae and in Atropa belladonna. Their potential ecological significance is discussed.
