Abstract
AbstractIn a screening for biologically active metabolites of the genusChondromyces, two novel metabolites, chondrochloren A (1) and B (2), were isolated from several strains ofC. crocatus. Compounds1and2are unique chloro‐hydroxy‐styryl amides of a highly modified C14carboxylic acid, which comprises an unsaturated ketone, two hydroxy, two methoxy and three methyl groups. After assignment of the absolute configuration of both carbinol stereocenters by Mosher’s method, NMR spectroscopic data combined with MM2 calculations allowed the prediction of the preferred conformation in solution.
