Ozonolysis of ethyl vinyl ether (7a) in the presence of the O-methylated oxime of cyclohexanone (8) afforded N-methoxy-1,2-dioxa-4-azaspiro[4.5]decane (9a), and ozonolyses of the O-methylated dioximes of 1,4- and 1,5-dicarbonyl compounds (10ae) afforded N-methoxylated bicyclic 1,2,4-dioxazolidines (12ae).
