  Divergent Cyclization Reactions of Morita–Baylis–Hillman Carbonates of 2-Cyclohexenone and Isatylidene Malononitriles

  摘要：

  Zwitterionic dienolates generated from Morita-Baylis-Hillman carbonates of cyclohexen-2-one and a phenolic tertiary amine catalyst underwent divergent cyclization reactions with isatylidene malononitriles. A new [4 + 2] stepwise cyclization process was disclosed to deliver complex bridged spirooxindoles after the initial delta'-regioselective Rauhut-Currier-type reaction with N-methyl electrophiles by the catalysis of beta-isocupreidine, while spirooxindoles incorporating an aromatic chromene motif were generated with N-MOM acceptors in the presence of alpha-isocupreine through different domino transformations.

  α‐Cyano ketones have been used for the first time as Michael donors in the construction of chiral spiro compounds. In the presence of only 2 mol‐% of a chiral multifunctional organocatalyst, chiral spiro[4H‐pyran‐oxindole] derivatives were prepared in excellent yields with good‐to‐excellent enantioselectivities. This method provides a new approach to the synthesis of chiral spirocyclic oxindoles.

  the intermolecular cross Rauhut-Currier reaction of 2-cyclopentenone and isatin-based alkylidene malononitriles. The resulting chiral adducts were sequentially assembled with diverse electron-deficient olefins to furnish highly enantioenriched cyclohexane derivatives (up to 96:4 er, >19:1 dr). A similar catalytic system of 2-mercaptobenzoic acid and quinine was further developed for the reaction of

  A diastereo- and enantio-selective domino Michael-cyclization–tautomerization reaction of isatylidene malononitriles with α,α-dicyanoalkenes catalyzed by a cinchona alkaloid-derived bifunctional thiourea catalyst has been developed. A series of multi-functionalized spiro oxindole diene derivatives have been obtained in good to excellent yields (up to 97%) with good to excellent enantioselectivities (up to 96%) as well as good diastereoselectivities (up to 7.9 : 1). In addition, an anomalous temperature effect on the enantioselectivity has also been studied for this transformation.
