Abstract:

A new pulvinic acid derivative, pulvinamide, has been identified as a constituent of Pseudocyphellaria crocata. With the possibility that pulvinamide is a key biosynthetic intermediate a more detailed pathway for the biogenesis of pulvinic acid and its derivatives is proposed, i.e. stepwise aldol-type of condensation of 1 mole phenylpyruvic acid with 1 mole pyridoxal-bound phenylalanine to give a quinoneimine analogue of polyporic acid which, after oxidative cleavage, would yield bound pulvinamide as the immediate precursor of the free pulvinic acid derivatives.
