  描述：

  2-[环己基(甲基)氨基]苯甲醛 、 4-甲苯磺酰乙腈 在 三乙胺 作用下， 以 乙醇 为溶剂， 以95%的产率得到1-methyl-3-[(4-methylphenyl)sulfonyl]-1,2,3,4-tetrahydrospiro(quinoline-2,1'-cyclohexane)-3-carbonitrile

  名称：

  A novel tert-amino effect based approach to 1,2,3,4-tetrahydroquinoline-2-spirocycloalkanes

  摘要：

  An interaction of 2-[cyclohexyl(methyl)amino]benzaldehydes with substituted acetonitriles X-CH2CN (X=CN, Tos, hetaryl) was found to yield 1-methyl-1,2,3,4-tetrahydrospiro(quinoline-2,1'-cyclohexane)-3-carbonitriles. The corresponding spiroquinoline-2,1'-cyclopentane analogues were obtained similarly starting from 2-[cyclopentyl(methyl)amino]benzaldehydes. The reaction was assumed to proceed via initial Knoevenagel condensation and further ring closure of the formed adduct according to the tert-amino effect mechanism. The structure of the prepared compounds was confirmed unambiguously by X-ray crystallographic study. (c) 2006 Elsevier Ltd. All rights reserved.

  functionalization triggered by sequential [1,5]‐ hydride shift /cyclization sequence using ortho amino benzaldehydes and active methylene compounds such as 2‐coumaranone, 4‐hydroxycoumarin, 3‐coumaranone, and 3‐isochromanone. This protocol provides a Lewis acid catalyst‐free straight forward one‐pot reaction in cases of 2‐coumaranone and 4‐hydroxycoumarin, Lewis acid‐catalyzed stepwise reaction for 3‐coumaranone
