A domino approach for the synthesis of naphtho[2,1-b]furan-2(1H)-ones from azlactones
摘要:
A domino approach to naphtho[2,1-b]furan-2(1H)-one derivatives from (Z)-4-arylidene-2-phenyl-5(4)-oxazolones (azlactones) and 2-naphthols catalyzed by p-TSA with reasonably moderate to high yields, has been developed. This protocol illustrates attractive features including a unique and convenient process. (C) 2014 Published by Elsevier Ltd.

An efficient synthesis of naphtho[2,1-<i>b</i>]furan-2(1<i>H</i>)-ones catalysed by Nafion-H supported on silica-coated super paramagnetic iron oxide nanoparticles
A one-pot procedure is descibed for the synthesis of naphtho[2,1-b]furan-2(1H)-ones via a multicomponent reaction of aryl aldehydes, hippuric acid, acetic anhydride and β-naphthol in the presence of Nafion-H supported on silica-coated superparamagnetic iron oxide nanoparticles undermicrowaveirradiation. The catalyst can be recovered easily and reused several times without significant loss of catalytic
描述了通过芳醛、马尿酸、乙酸酐和β-萘酚在Nafion-存在下的多组分反应合成萘并[2,1-b]呋喃-2(1H)-酮的一锅法。 H 在微波辐射下负载在二氧化硅包覆的超顺磁性氧化铁纳米颗粒上。该催化剂可以很容易地回收并重复使用多次,而不会显着降低催化活性。
