N2 - (Chemical Equation Presented) A silver lining: [2+2] Cycloadditions of imines 2 to (alkoxymethylene)cyclopropanes 1 proceed readily at 80°C and ambient pressure to furnish spirocyclopropanated 2-alkoxyazetidines 3 in good to excellent yields. The same reaction can be brought about at 30°C in the presence of a catalytic amount of [Ag(fod)] (fod = 6,6,7,7,8,8,8-heptafluoro-2, 2-dimethyl-3,5-octanedionato).
