Synthesis of 2-alkoxy-Δ3-dihydropyrans from Δ2-dihydropyrans

  • V. B. Mochalin

Some 2-alkoxy-Δ3-dihydropyrans can be easily obtained by bromoalkoxylation with N-bromosuccinimide in the presence of alcohols of various Δ2-dihydropyrans and subsequent dehydrobromination of the resulting alkoxybromides with alcoholic alkali. The stereospecificity of this transformation was studied in the case of 6-substituted Δ2-dihydropyrans.
