  Design and synthesis of a bis(hydroxyphenyl)diamide bearing a pendant thiazolium unit; application to the catalytic asymmetric intramolecular Stetter reaction

  摘要：

  The bis(hydroxyphenyl)diamide architecture constitutes as a privileged ligand that promotes a number of catalytic asymmetric transformations in combination with rare-earth metals. A new diamide analog armed with a carbene catalytic function derived from a thiazolium unit was designed, synthesized, and applied to the catalytic asymmetric intramolecular Stetter reaction. Cooperative work between the carbene function and hydrogen bonding interactions was suggested to give the enantioenriched chroman derivatives. (C) 2014 Elsevier Ltd. All rights reserved.

  2-(烯氧基)苯甲醛芳腙的分子内1,3-偶极环加成和分子内烯反应

  摘要：

  2-(3-Aryl-2-propenyloxy)苯甲醛（或1-萘醛）芳腙通过其1,3-偶极互变异构体偶氮甲亚胺与烯基发生分子内环加成反应。在反应条件下，初始环加合物转化为脱氢化合物。另一方面，将氰基或乙氧基羰基代替芳基引入邻丙烯氧基的3-位，分别得到3-氰甲基-4-色满酮芳基腙或相应的乙氧基羰基衍生物。这些腙的形成被解释为分子内烯反应。反应过程取决于烯基取代基的性质。

  4-tetrahydro[1]benzopyrano(or naphtho[1′,2′:5,6]pyrano)[4,3-c]pyrazoles. The reaction of 1 with methylhydrazine sulfate gave the corresponding 2-methyl derivatives. Analogous intramolecular [3++2] cycloadducts were obtained from the reaction of 2′-(alkenyloxy)acetophenones with arylhydrazine hydrochlorides. Intermolecular [3++2] cycloadducts were also obtained from a reaction mixture of 1-naphthaldehyde, arylhydrazine

  A highly enantioselective intramolecular Stetter reaction of aromatic and aliphatic aldehydes tethered to different Michael acceptors has been developed. Two triazolium scaffolds have been identified that catalyze the intramolecular Stetter reaction with good reactivity and enantioselectivity. The substrate scope has been examined and found to be broad; both electron-rich and -poor aromatic aldehydes

  2-(3-Aryl-2-propenyloxy)benzaldehyde (or 1-naphthaldehyde) arylhydrazones undergo an intramolecular cycloaddition reaction via their 1,3-dipolar tautomers, azomethine imines, to the alkenyl group. Initial cycloadducts were converted to dehydrogenated compounds under the reaction conditions. On the other hand, introduction of cyano or ethoxycarbonyl groups instead of the aryl group into 3-position of
