Preparation of enol ethers, useful in e.g. pharmaceutical, agrochemical or cosmetics synthesis or as monomer for polymer, uses alkali alcoholate in polar aprotic solvent in reaction of alcohol with alkyne and/or alkadiene

摘要

Preparation of enol ethers (I) by reacting alcohols (II) with alkynes (IIIA) and/or alkadienes (IIIB) and is carried out in the presence of an alkali alcoholate and a polar aprotic solvent. Preparation of enol ethers of formula (I) by reacting alcohols of formula (II) with alkynes of formula (IIIA) and/or alkadienes of formula (IIIB) of the given formulae is carried out in the presence of an alkali alcoholate and a polar aprotic solvent. R1-R3 = H or an organic group containing carbon; and R4 = optionally substituted alkyl.
