[4 + 2] cycloaddition of benzofuran-derived azadienes with vinyl benzoxazinanones, which represents a rare highly stereoselective cycloaddition of this class of fused azadienes as a two-atom synthon. The use of a phosphoramidite ligand bearing a chiral secondary amine with a simple biphenyl backbone proved to be the key to construct the novel spirocyclic tetrahydroquinoline scaffold containing three
benzoxazinanones (4) with sulfur ylides (2) is reported. While the reactions of 4-vinyl/4-CF3 benzoxazinanones (1a/1c) with 2 furnished the 3-vinyl/3-CF3 indolines (3a/3c), via an attack on the C1 carbon of the π-allyl/benzyl zwitterionic intermediates, 4 was converted into 4-trifluoromethyl-dihydroquinolines (5) in good yields via an attack on the C3 carbon of the π-allyl intermediate. The corresponding
Highly Diastereoselective Synthesis of Trifluoromethyl Indolines by Interceptive Benzylic Decarboxylative Cycloaddition of Nonvinyl, Trifluoromethyl Benzoxazinanones with Sulfur Ylides under Palladium Catalysis
diastereoselective synthesis of trifluoromethyl-substituted indolines under palladium catalysis is disclosed. The reaction proceeds by interceptive decarboxylative benzylic cycloaddition (IDBC) of nonvinyl, trifluoromethyl benzoxazinanones with sulfur ylides. The palladium−π-benzyl zwitterionic intermediates are suggested for this transformation, and this would be the first example of an IDBC reaction.
