| Abstract: | In the presence of catalytic amount of indium(III) Lewis acids, the four component reaction of aldehydes, isocyanides, trimethylsilyl azide and aliphatic alcohols smoothly proceeded to give alkoxylated 1H-tetrazole products in good yields. In particular, In(OTf)3 and In(ONf)3 showed notably high level of catalytic activity in this reaction. |
