Synthesis of imidates (imino ethers)
A simple and reliable protocol for regioselective O-alkylation of amides provides the corresponding imidates. Its scope and efficiency is demonstrated on a number of substrates.

A mild, one-pot cyanoimidation of aldehydes using cyanamide as a nitrogen source and NBS as an oxidant was achieved in high yields without the addition of a catalyst. Subsequently, the substituted N-cyanobenzimidate products may also undergo a cyclization reaction to give 1,2,4-triazole derivatives in high yields.
