• Lewis acid-catalyzed tandem synthesis of 9-sulfonylamino- and 9-arylfluorenes

  A Lewis acid-catalyzed three-step tandem synthesis of 9-arylfluorene was developed by simply heating a mixture of 2-formyl biphenyl, TsNCO and an arene. In the absence of arene, a two-step tandem synthesis of 9-sulfonylaminofluorene was achieved. These advances were mainly attributed to the discovery of an anhydrous synthesis of N-tosyl arylaldimines from TsNCO and arylaldehydes.

  通过简单地加热2-甲酰基联苯，TsNCO和芳烃的混合物，开发了路易斯酸催化的三步串联合成9-芳基芴的方法。在没有芳烃的情况下，实现了两步串联的9-磺酰基氨基芴的合成。这些进展主要归因于从TsNCO和芳基醛无水合成N-甲苯磺酰基芳基亚胺的发现。

  An efficient and expeditious boron trifluoride etherate (BF3⋅Et2O) catalyzed one‐pot reaction for the synthesis of N‐tosyl‐9‐aminofluorenes and anthracene derivatives from in situ generated N‐tosylbenzaldimines via an aza‐Friedal–Crafts reaction has been developed. The catalytic reaction shows high substrate tolerance with excellent yields.

  A simple AlCl3‐catalyzed condensation/cyclization cascade process between aldehydes and sulfonamide is reported, in which two new bonds and one five‐membered ring are simultaneously formed with water as the byproduct. This method provides a rapid access to indenamine and 9‐aminofluorene derivatives. Additionally, these products can be transformed into corresponding indanones and fluorenones under the
