  One-pot synthesis of pyrrolidino- and piperidinoquinolinones by three-component aza-Diels–Alder reactions of in situ generated N-arylimines and cyclic enamides

  摘要：

  An efficient synthesis of hexahydropyrrolo[3,2-c]quinolin-2-ones and hexahydropyridino[3,2-c]quinolin-2-ones has been developed in moderate to high yields by one-pot two-step aza-Diels-Alder reactions of N-arylimines, formed in situ from anilines and benzaldehydes, with cyclic enamides, formed in situ from 5-hydroxypyrrolidin-2-ones and 6-hydroxypiperidin-2-ones by BF3 center dot OEt2-promoted dehydration in dichloromethane at room temperature. The hexahydropyrrolo[3,2-c]quinolin-2-ones were formed as a single exo-stereoisomer in most cases and hexahydropyridino[3,2-c]quinolin-2-ones were formed as a mixture of exo- and endo-isomers favoring the endo-diastereomer.

  Cyclic imides were selectively reduced to the corresponding ω‐hydroxylactams in high yields with (EtO)3SiH (triethoxysilane) or PMHS (polymethylhydrosiloxane) under catalysis of zinc diacetate dehydrate [Zn(OAc)2⋅2 H2O] (10%) and tetramethylethylenediamine (TMEDA) (10%). This catalytic protocol showed good functional group tolerance as well as excellent regioselectivity for unsymmetrical imides bearing

  A metal free coupling of heteroaromatic N-tosylhydrazones with thiols is presented. A convenient synthetic route to synthesize heteroaryl N-tosylhydrazones is also showed. Valuable thioethers with pyrroles, pyridines, thieno[2,3-b]pyridines, imidazo[1,2-a]pyridines, and 6H-thieno[2,3-b]pyrroles derivatives were synthesized in good yields. This coupling reaction can be carried out in a one-pot fashion
