(N-Isocyanimino)Triphenylphosphorane as an Efficient Reagent for the Preparation of N-Benzyl-1-Phenyl-1-(5-Phenyl-1,3,4-Oxadiazol- 2-yl)Methanamine Derivatives via in-Situ Generation of Densely Functionalized Iminophosphoranes
摘要:
A novel isocyanide-based four-component reaction between (N-isocyanimino) triphenylphosphorane, benzyl amine, benzaldehyde derivatives, and various carboxylic acids efficiently provides N-benzyl-1-phenyl-1-(5-phenyl-1,3,4-oxadiazol-2-yl)methanamine derivatives in good yields without using any catalyst or activation. The reaction can be carried out as a simple one-pot protocol at room temperature.
