The 1,3-dipolar cycloaddition reaction of a non-stabilized azomethine ylide 4a, formed in situ from N-(methoxymethyl)-N-(trimethylsilylmethyl)benzylamine 5 and a catalytic amount of trifluoroacetic acid, with aromatic aldehydes 3 gives rise to N-benzyl-5-

The first example of the 1,7-electrocyclisation of a non-stabilised azomethine ylide, e.g. 2, onto a nitro group, to give a 1,2,6-oxadiazepine intermediate, e.g. 4, is reported. Subsequent ring contraction results in the formation of the indazole-N-oxides 5, 12, and 14.
