Solvent‐Free Microwave Michael Addition Between EMME and Various Nucleophiles
摘要:
Michael addition reaction between EMME and various O, S, N nucleophiles were investigated in the presence of catalysts such as KF, KOH, or K(OCCH3)(3) under solvent-free conditions either neat or on alumina as solid support. Compared to low reactivity of alcohols (40 to 80% yields according to aliphatic chain), aniline or thiophenol. gave good to excellent yields (90-99%).
