Abstract

A convenient and highly efficient protocol for one-pot synthesis of some novel N-heterocycle methyl-O-oxime ethers is described. In this method, three-component coupling of different types of ketoximes, with methylene iodide and nitrogen heterocycles, including imidazoles, benzimidazole, benzotriazole, and theophylline in the presence of an equimolar mixture of K2CO3/Et3N in refluxing MeCN furnished the corresponding N-heterocycle methyl-O-oxime ethers in good yields. This methodology is highly efficient for the synthesis of various structurally diverse N-heterocycle methyl-O-oxime ethers. The results of quantum mechanical studies on reaction intermediates are discussed.
