Chemistry of (Glycidyloxy)propiolactones. An Intramolecular Transfer of Alkoxy Group in the Alcoholysis and Reduction Reactions

An interesting intramolecular transfer of an acetal alkoxy group is observed in the alkaline alcoholysis and in reduction by LiAlH4 of α-methyl-α-((1-tert-butoxy-2-methyl-2,3-epoxypropyl)oxy)-β-propiolactone (3a).With either methanol or ethanol and NaOH at 30 deg C, the (glycidyloxy)propiolactone 3a cleaves to produce α-methylglycidaldehyde and either methyl or ethyl α-tert-butoxy-β-hydroxyisobutyrate.Reduction with LiAlH4 at 30 deg C also cleaves 3a, this time with partial reduction to give 2-methyl-2,3-epoxypropanol (6) and 2-methyl-2-tert-butoxypropane-1,3-diol (7).In each case the tert-butoxy group has been transferred to the α carbon of the β-lactone portion of 3a.
