Biosynthesis of a linoleic acid allylic epoxide: mechanistic comparison with its chemical synthesis and leukotriene A biosynthesis s⃞ Reaction/Examples Ring Opening with an Acid The Way Taught in CHEM 2127. As taught in CHEM 2127, acid-catalyzed epoxide opening follows an S N 1 mechanism. An epoxide is a cyclic ether with three ring atoms. Synthesis The dominant. The reaction proceeds via what is commonly known as the Butterfly Mechanism. Lewis Acid Induced Epoxide Rearrangement for Complex Molecule Synthesis Research by M.E. Jung and C.P. Lee, Org.
