An efficient one-pot synthesis of a variety of quinoline carboxylates was accomplished by Cu(OTf)2-catalyzed reactions of Michael addition/cyclization/aromatization between 2-aminoaryl carbonyls and alkynyl carboxylates. This methodology offers several significant advantages, namely, ease of handling, mild reaction conditions, enhanced reaction rates, and use of an effective and non-toxic catalyst

AbstractThe phosphine‐catalyzed [3+2] annulation of electron‐deficient alkynes with N‐hydroxyphthalimide has been developed to give a variety of pharmaceutically attractive 3a‐hydroxyisoxazolo[3,2‐a]isoindol‐8(3aH)‐ones in good to excellent yields.magnified image
