✦ Synopsis

It was recently suggested (1) that cordiachromes, a novel group of terpenoid quinones, e.g., I, from Cordia millenii, probably arise by condensation of a benzenoid precursor with -~ geranylpyrophosphate and subsequent oxidative cyclization of an allylic methyl group. From ether extracts of the heartwood of a related species, Cordia alliodora, a new, colorless phenol (m.p. 87"), alliodorin, has now been isolated and structurally identified as II. Alliodorin, therefore, is probably an immediate precursor to the cordiachromes, and its isolation provides significant experimental support for the proposed biosynthetic origin of these substances.
