Some properties of 2-alkoxy-1-alken-3-ols

Conclusions The reaction of 2-alkoxyacroleins with Grignard reagent gave some new 2-alkoxy-1-alken-3-ols, which in the presence of p-toluenesulfonic acid are cyclodimerized to 2,3,5,6-tetraalkyl-2,5-dialkoxy-1,4-dioxanes, which tend to cleave ethanol to give 2,3,5,6-tetraalkyl-5-alkoxy-1,4-dioxenes.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2534–2538, November, 1980.The authors express their gratitude to V. I. Lavrent'ev and V. Yu. Vitkovskii for taking the mass spectra.
