Question

Epoxidation is a stereospecific reaction. Since the oxygen transfer occurs in a concerted step, the stereochemistry of the alkene is preserved in the epoxide. Thus, choosing a cis- vs. trans-alkene will provide different stereochemical outcomes. WS 2.22: Two diastereomers, cis-pent-2-ene vs. trans-pent-2-ene, are treated with mCPBA, followed by $NaOCH_3$. Compare the stereochemistry of the products obtained from the two diastereomers.
