Synthesis of a 105 membered library of 1,2-dihydroisoquinolines is described. The 1,2-dihydroisoquinoline compounds have been prepared in good yields using a Lewis acid and organocatalyst-cocatalyzed multicomponent reaction of 2-(1-alkynyl)benzaldehydes, amines, and ketones. Various indoles have also been employed as pronucleophiles, furnishing 1-(3-indolyl)-1,2- dihydroisoquinolines. The halogen functionality present in some of the synthesized compounds allows for further diversification by palladium-catalyzed Suzuki-Miyaura and Sonogashira cross-couplings to give more diversified 1,2-dihydroisoquinoline derivatives. © 2011 American Chemical Society.

Abstract
Synthesis of a 105 membered library of 1,2-dihydroisoquinolines is described. The 1,2-dihydroisoquinoline compounds have been prepared in good yields using a Lewis acid and organocatalyst-cocatalyzed multicomponent reaction of 2-(1-alkynyl)benzaldehydes, amines, and ketones. Various indoles have also been employed as pronucleophiles, furnishing 1-(3-indolyl)-1,2- dihydroisoquinolines. The halogen functionality present in some of the synthesized compounds allows for further diversification by palladium-catalyzed Suzuki-Miyaura and Sonogashira cross-couplings to give more diversified 1,2-dihydroisoquinoline derivatives. © 2011 American Chemical Society.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
