2-Phenylethylamides of a novel lipid acid; atrial stimulants from the soft coral Sinularia flexibilis

Abstract

Three amides derived from tyramine, 4-(2-aminoethyl)-2-methoxyphenol and 5-(2-aminoethyl)-2-methoxyphenol and a novel lipid acid, (Z)-3- methyldodec-2-enoic acid, were isolated from the soft coral Sinularia flexibilis. The structures, obtained by spectral methods, were confirmed by synthesis.
