Abstract
Two pyrrololactams, likely degradation products of more complex known guanidines, were isolated from several marine sponges. 5-Bromo- and 4,5-dibromopyrrole-1-carboxylic acid methyl esters were also isolated. A complex guanidine metabolite, poorly soluble in DMSO, was found to give sharp, reproducible nmr spectra in acid media.
