 Title    Synthesis and Structure of Chiral Silatranes Derived from Terpenes  
 Abstract    Starting with the chiral pool compounds (—)-menthone, (—)-limonene, (—)-/3-pinene, and (—)-carvone, new homochiral triethanolamine derivatives were obtained and converted to chi­ ral silatranes. These silatranes were characterized by crystal structure analyses and NMR techniques. Conformational analyses in the solid terpene residues determine the direction of the ring

 Title    Chemical Intra-Mediterranean Variation and Insecticidal Activity of Crithmum maritimum  
 Abstract    The chemical composition of the volatile metabolites of Crithmum maritimum harvested from several geographic localities along the M editerranean coasts was studied by GC and GC-MSD. The major oil constituents were found to be dillapiole, y-terpinene, sabinene, limo-nene and ß-phellandrene. The W estern populations were richer in dillapiole, whereas the Southern collections were characterized by increased amounts of thymol methyl ether and y-terpinene. The Italian chemical profiles differentiated by the significant contributions of carvacrol methyl ether and isoterpinolene. The essential oils were also investigated for their insecticidal activity and their repellency against Pheidole pallidula (Nylander) ants and found to possess significant activity.
