Four component reaction of aldehydes, isocyanides, Me3SiN3, and aliphatic alcohols catalyzed by indium triflate
摘要:
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. (C) 2012 Elsevier Ltd. All rights reserved.
