Synthesis of diheterocyclic compounds based on triazolyl methoxy phenylquinazolines via a one-pot four-component-click reaction.
A facile and highly efficient method for one-pot four-component synthesis of triazolyl methoxy phenylquinazolines is described. A mixture of aromatic propargylated aldehydes, different azides, 2-aminobenzophenone derivatives, and ammonium acetate were condensed in the presence of catalytic amounts of acidic ionic liquid, 1-methylimidazolium trifluoroacetate, ([Hmim]TFA), and Cu(OAc)(2)/sodium ascorbate to afford the corresponding products in excellent yields. This methodology is highly efficient for structurally diverse azides.
