Efficient synthesis of 2-substituted 2,3-dihydro-4-quinolones as potential intermediates for 2-substituted 1,2,3,4-tetrahydro-4-quinolone antitumor agents

Abstract

An efficient method for the synthesis of optically active 2-substituted 2,3-dihydro-4-quinolones has been developed. The key features include the introduction of a chiral side chain and the construction of quinolone skeleton by Mitsunobu alkylation and hydroarylation, respectively.
