  A modified Bischler-Napieralski procedure for the synthesis of 3-aryl-3,4-dihydroisoquinolines

  摘要：

  A modification of the Bischler-Napieralski reaction for the cyclization of (1,2-diphenylethyl)amides to the 3-aryl-3,4-dihydroisoquinolines is presented. Elimination of the amide group as the nitrile via the retro-Ritter reaction is avoided by its conversion to an N-acyliminium intermediate with oxalyl chloride-FeCl3. Removal of the oxalyl group in refluxing MeOH-sulfuric acid provides the 3,4-dihydroisoquinolines in moderate to high yields. The method is also highly effective with (2-phenylethyl)amides.

  An air‐stable, simple (RP)‐mentylbenzylphosphinate, readily available in large quantities, can efficiently induce the rhodium‐catalyzed asymmetric hydrogenation of α‐acetamidocinnamates with high enantioselectivity (up to 99.6 % ee). Intramolecular hydrogen bonding plays an important role in this asymmetric induction.

A range of trisubstituted carbocyclic olefins bearing different functional groups were also reduced delivering products with >99% ee’s. Pharmaceutically important chiral primary amines have also been prepared using the hydrogenation/hydrolysis method
