The reaction of 4-methyl-4-(4-methyl-3-pentenyl)-5-methylen-1,3-dioxolan-2-one 1a with primary amines 2 leads to the corresponding 4-hydroxy-4-methyloxazolidin-2-ones 3 which are transformed by intramolecular amidoalkylation into 1-oxa-3-azapentalen-2-ones 4 and 5, potential precursors of cyclopentane cis-2-amino alcohols.
