The corresponding acetylenic aziridino hydroxy carbinols were obtained by the reaction of aziridine, 2,2-dimethylaziridine, and methyl aziridine-2-carboxylate with 4-hydroxy-4-methylpent-2-yn-1-al and 3-(1-hydroxycyclohexyl)prop-2-yn-1-al. It is shown that the latter at room temperature undergo isomerization with time to 2-hydroxy-4-aziridino-5,5-dialkylduiydrofurans. The isomerization of acetylenic aziridinocarbinols, which includes an intermediate step involving retrodecomposition of the aziridino (hydroxy) carbinols to the starting aldehydes and aziridines, was investigated by dynamic NMR spectroscopy.
