Stereochemistry of the Dibenzopyrrocoline Alkaloids Cryptaustoline and Cryptowoline

Abstract
Stereochemistry of the dibenzopyrrocoline alkaloids, (-)-cryptaustoline (1) and (-)-cryptowoline (2), isolated from the Australian shrub Cryptocaria bowiei is deduced both as 7R,13S configuration with cis B/C ring structure based on the analysis of proton-nmr spectra of synthetic materials.
