A new method for the synthesis of benzofuran-3(2H)-ones under microwave conditions was developed. The reaction conditions were screened, and the scope of benzoate substrates was investigated. The results showed that our method could provide rapid access to these important dihydrobenzofuranones in 43% to 58% yields.
Convenient synthesis of N-benzyl-1,4-dihydropyridines, cyclohexenones, and bicyclo[3.3.1]nonan-3-one derivatives from 1-aza-1,3-butadienes

Readily available 1-aza-1,3-butadienes (enimines) react with methyl acetoacetate and acetylacetone in the presence of catalytic amounts of lithium iodide to form in high yields unsymmetrically substituted 1,4-dihydropyridines or cyclohexenones. The reacti
