Abstract:
(4,8,13)-13-Methyl-16-oxo-17-norkaurane-18-carboxylic acid (isosteviol) and its methyl ester were reacted with benzylamine and hydroxylamine to obtain the corresponding E-stereoisomeric 16-ketimines. Isosteviol benzylimine and oxime form individual 1:1 H-bonded complexes with methanol and water, respectively.
