Abstract:
Candipolin, a mycelial metabolite of the fungus Penicillium canadense, is N-benzoyl-O-(N-benzoyl-L-phenylalanyl)-L-phenylalaninol Its structure was deduced from spectroscopic and degradative studies and confirmed by synthesis. Esterification of N-benzoyl-L-phenyl-alaninol with the imidazolide of N-benzoyl-L-phenylalanine yielded a mixture of candipolin and its epimer, the latter arising by racemisation at the phenylalanine centre. Epi-candipolin crystallised from the mixture more easily than candipolin, making isolation of the desired product rather difficult. Candipolin was obtained free from its epimer by esterification of N-benzoyl-L-phenylalaninol with the imidazolide of N-CBZ-L-phenylalanine, followed by selective removal of the CBZ-group and benzoylation.
