In continuation of our studies on MurrayaexoticaLinn. (Syn. M. paniculata) from which we reported mexoticin1 (1), hibiscetin heptamethyl ether,2 carbazole alkaloids, murrayazoline, mahanimbine and girinimbine,3 we now report the structure of a newantibiotic dimeric coumarin named mexolide (2) having an unusual cyclohexene system similar to that in cyclobissuberodiene4 [thamnosin5 (3)].
