Two novel bis(bibenzyls) named paleatins A (1) and B (2) have been isolated from the liverwort, Marchantia paleacea var. diptera. Their structures have been establishied by a combination of high-resolution NMR spectra and chemical degradation. A total synthesis of paleatin A has been accomplished in ten steps.
