  Per-6-amino-β-cyclodextrin as a Chiral Base Catalyst Promoting One-Pot Asymmetric Synthesis of 2-Aryl-2,3-dihydro-4-quinolones

  摘要：

  A highly efficient one-pot synthesis of enantiomerically enriched 2-aryl-2,3-dihydroquinolin-4(1H)-ones has been carried out for the first time using per-6-ABCD as a supramolecular host, chiral base catalyst, and a reusable promoter to give the corresponding scaffold with high yield (up to 99%) and enantiomeric excess (up to 99%). The catalyst is recovered and reused without loss in its activity.

  Primary amino acids are found to be good enantioselective catalysts for the direct asymmetric Mannich reaction between 2-amino acetophenone and aldehydes. The 2-aryl-2,3-dihydro-4-quinoline products are obtained in moderate to good yields and good to high enantioselectivities with 10 mol% of the primary amino acid catalyst under mild reaction conditions.
