The /sup 13/C NMR spectra analysis of the new bis(indole) alkaloid flexicorine and of its chemically modified derivatives were used to determine the structure of the natural base. Flexicorine is, apparently, the first 10'-hydroxy N'-unsubstituted indoline which preferentially exists in the original iminoquinone form. 2 tables.
