METHODS OF PREPARING PARA-XYLENE FROM BIOMASS

Methods or preparing para-xylene from biomass by carrying out a Diels-Alder cycloaddition at controlled temperatures and activity ratios. Methods of preparing bio- terephthalic acid and bio-poly(ethylene terephthalate (bio-PET) are also disclosed, as well as products formed from bio-PET.

A Total Synthesis of (+/-)-Faranal, the True Trail Pheromone of Pharaoh's Ant, Monomorium pharaonis

A relatively short total synthesis of the true trail pheromone of Pharaoh's ant, (+/-)-faranal is reported.The carbon skeleton was assembled by a Wittig condensation between (Z)-6-methyloct-5-en-2-one (4) and the 5-carboxypentylphosphonium salt (15).The ketone (4) was prepared in 'one-pot' and in a stereoselective manner using vinyl cuprate chemistry, while the relative stereochemistry of the two methyl substituents in the phosphonium salt (15) was established by using the Diels-Alder adduct (16) of buta-1,3-diene and maleic anhydride, which, after reduction and oxidative cleavage of the resulting cis-1,2-dimethylcyclohex-4-ene (18), gave only meso-3,4-dimethyladipic acid (19); this in turn was converted into the salt (15) in six straight-forward steps.
