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 (10a-e) afforded N-methoxylated bicyclic 1,2,4-dioxazolidines (12a-e).

The intermolecular coupling of a variety of ketones with some types of O-methyl oximes took place when a mixture of both components was electrochemically reduced in i-PrOH with an Sn cathode.The product, β-methoxyamino alcohol was easily converted to β-amino alcohol by simple reduction.A chiral ligand effective for the enantioselective addition of diethylzinc to an aldehyde was easily obtained from the product formed by the electroreductive coupling of (-)-menthone with O-methylacetaldoxime.The intermolecular coupling of a ketone with a N,N-dimethylhydrazone or nitrone was also promoted by the electroreduction.Furthermore, the electroreductive coupling of a carbonyl group with an intramolecular O-methyl oxime moiety gave the corresponding cyclized product stereoselectively.
