Popis:	4,5-Epoxy-2-hexenoic acid esters add alcohols (in the presence of the alkoxide) and diazomethane to the double bond with retention of the oxirane ring; alkoxylation products and Δ2-pyrazolines are formed. The alkoxide anion and diazomethane add to the positively polarized β-carbon atom of the conjugated ether. The structures of the synthesized compounds were proved by their IR, UV, and PMR spectra.
