bases, TBD and MTBD were found to be highly efficient catalysts in the Michael addition of azoles with α,β-unsaturated nitriles and esters. The factors influencing regioselectivity have been elucidated, and some new azole-Michael adducts were synthesized. These were shown to be useful starting compounds for the regioselective N-alkylation of the corresponding azoles.
