Single-flask polyfunctionalization of the imidazole ring; a streamlined route to the antitumor agent carmethizole
摘要:
Three sequential treatments of an N-protected tribromoimidazole with n-BuLi / electrophile in a 1-pot process leads to N-protected 2,4,5-trisubstituted imidazoles. The method can be applied to the preparation of the immediate precursor of carmethizole.
