Lithium perchlorate/diethylether-catalyzed three-component coupling reactions of aldehydes, hydroxylamines and trimethylsilyl cyanide leading to α-cyanohydroxylamines
Three-component coupling reactions of aldehydes, hydroxylamines and trimethylsilyl cyanide proceeded smoothly in the presence of lithium perchlorate/diethylether solution (5 M) to afford alpha-cyanohydroxylamine derivatives in high yields. (C) 2000 Elsevier Science Ltd. All rights reserved.
