Abstract. 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.
