Squeeze out the water! Chiral phosphoric acid catalyzed tandem double Friedel–Craftsreactions between indoles and 2‐formylbiphenyls were realized under mild conditions. The 9‐(3‐indolyl)fluorenederivatives were obtained in good yields and up to 96 % ee, leaving water as the sole by‐product (see scheme).
The invention relates to substituted aryl acids as useful pharmaceutical compounds for treating respiratory disorders, pharmaceutical compositions containing them, and processes for their preparation.
