Received: 02 May 2012 – Published in Atmos. Chem. Phys. Discuss.: 07 Jun 2012Abstract. Isoprene epoxydiol (IEPOX) isomers are key gas-phase intermediates of
isoprene atmospheric oxidation. Secondary organic aerosols derived from such
intermediates have important impacts on air quality and health. We report
here convergent and unambiguous pathways developed for the synthesis of
isomeric IEPOX species and the rearrangement products cis- and
trans-3-methyl-3,4-dihydroxytetrahydrofuran in good yield. The availability of
such compounds is necessary to expedite research on isoprene atmospheric
oxidation mechanisms and subsequent aerosol formation as well as the
toxicological properties of the aerosols.
