영문초록

실온에서 방향족 알데히드, 말론니트릴과4-히드록시쿠마린을neat 실리카젤 속에서 one-pot반응시켜서 3,4-dihydropyrano[c]chromenes을 좋은 수율로 합성하였다.

기타언어초록

Highly efficient, three-component condensation of aromatic aldehyde, malononitrile and 4-hydroxycoumarin promoted by neat silica gel at room temperature is described. The method offers an excellent alternative to the synthesis of 3,4-dihydropyrano[c]chromenes. The reactions are fast and clean, and the products are obtained with good yield and purity.
