  Rapid synthesis of the tetrahydroquinoline alkaloids: angustureine, cuspareine and galipinine

  摘要：

  A one-pot method for the preparation of 1,2-substituted dihydroquinolines is described. This method features the C-2 addition of a range of organolithium reagents to quinoline followed by the in-situ addition of an electrophile. Standard palladium-catalysed hydrogenation, of the resultant 1,2-disubstituted dihydroquinoline adducts, generates the corresponding 1,2-disubstituted tetrahydroquinoline. A series of such compounds have been synthesised including the natural products; (+/-)-angustureine 1, cuspareine 2 and galipinine 3. (C) 2008 Elsevier Ltd. All rights reserved.

  Come full circle: A method for the nucleophilic amination of methoxy arenes was established by using sodium hydride (NaH) in the presence of lithium iodide (LiI). This method offers an efficient route to benzannulated nitrogen heterocycles. Mechanistic studies showed that the reaction proceeds through an unusual concerted nucleophilic aromatic substitution.

  Direct cc-alkylation of N-phenyl-tetrahydroisoquinoline with alkyl selenides of desired alkyl chain length and functionality is reported by photoredox catalysis. Construction of hexahydro pyrrolo- and pyrido-isoquinoline scaffolds along with indolines and tetrahydroquinolines is also described by intramolecular C(sp(3))-C(sp(3)) cross-couplings.
