What is Two New Tetracyclic Diterpenes from the Defense Secretion of the Neotropical Termite about?

OPerggmon Press Ltd. 1979. Prfnted in Great Britain. Chemical defense by the highly evolved nasute termite soldiers (lsoptera: Termitidae: Nasutitermitinae) is effected by squirting potential predators with an odorous sticky secre-ti0n.l This defense secretion, composed of monoterpene hydrocarbons and polyoxygenated cmbrene-derived diterpenes, has been analyzed in detail for several species representing the genera Nasutitenaes, Trinervitennes andGrallatotemes from Old and New World locations. 2-4 The -diterpene components are dome-shaped, possessing either the tricyclic trinervitane (e.g., .l)3 or 1 the two one tetracyclic kempane (e.g., 2)' carbon skeletons. = We now report the characterization o'? novel B,y-unsaturated ketones based on the kempane skeleton': 38-hydroxy-7B-kemp-8(9)-en-6- (2) and 2B-acetoxy, 3B-hydroxy-7B -kemp-8(9)-en-6-one (i).
