  Generation of 3-piperidine(methan)amines and cyclic 3-piperidine-methanamines as potential substance P antagonists

  摘要：

  A general method is described for the synthesis of 3-piperidine(methan)amines and their cyclic analogues. The 3,5-dichloro-2H-1,4-oxazin-2-ones 6 and 3-aryl substituted analogues are reacted with acetylenic dienophiles yielding pyridines. Further catalytic hydrogenation and functional group transformation (1) or substitution (2-3) with ring closure reactions (4) followed by hydrogenation provided the 2,3,5-cis substituted piperidines 1-3 and a cis substituted [3,4-c]pyrrolopiperidine 4. These compounds have recently raised great interest due to their Substance P antagonist profiles. (C) 1997 Elsevier Science Ltd.

  2（H）-1,4-Oxazin-2-ones的Diels-Alder环加成反应的研究

  摘要：

  各种在其3和6位带有一系列取代基的5-氯-2（H）-1,4-恶嗪-2-酮经历了Diels-Alder环加成反应，成为具有电子富集的2-azadiene组分，电子缺陷和电子中性的亲二烯体。这些反应以适度的区域选择性和立体选择性进行，以提供相对稳定且易于分离的桥连双环内酯环加合物。这些环加合物的化学操作提供了高度取代且功能丰富的哌啶。使用密度泛函理论（B3LYP / 6-31G *）通过计算研究了5-氯-2（H）-1,4-恶嗪-2-酮的环加成反应的区域和立体化学偏好。

  2,3- and 3,4-o-bis(chloromethyl)pyridines 3, produced via cycloaddition of the oxazinones 2 with propargyl chloride and 1,4-dichloro-2-butyne, were used as precursors of various pyridine o-quinodimethane analogues. The 2,3- and 3,4-dimethylenepyridine systems were generated via reductive 1,4-elimination with iodide and trapped in situ with various dienophiles to form the tetrahydroquinoline and -isoquinoline

  From oxazinones 4, precursors for pyridine o-quinodimethane analogues are made accessible via cycloaddition with 1,4-dichloro-2-butyne and propargyl chloride. Subsequent 1,4-elimination of the polyfunctional o-bis(chloromethyl)-pyridines affords both 2,3- and 3,4-dimethylene compounds, which are trapped in situ with various dienophiles.

  electrophilic catalysis avoiding reaction of the lactone function. The azadiene system in the 3-substituted 5-chloro-6-methyl-2H-1,4-oxazin-2-ones is shown to react easily with monosubstituted acetylenic compounds yielding polyfunctionalized pyridines in excellent yield via a cycloaddition-elimination process. The usually high regioselectivity and its dependence on the nature of the 3-substituent is discussed

  1,1,4,4-Tetrasubstituted cyclopenta[c]piperidines and the corresponding 4,4,7,7-pyrrolo[3,4-c]piperidines have been synthesised via cycloaddition of 5-chloro-6-methyl-3-phenyl-2H-1,4-oxazin-2-one with cyclopentene and 3-pyrroline derivatives, respectively, followed by reductive opening of the lactone-bridged adducts. The axial-equatorial conformational preferences of the substituents in these cis-fused bicyclic systems were opposite to those for the monocyclic piperidine analogues. The specific array of functional groups in the bicyclic aminoalcohols was used to accommodate, in stereocontrolled fashion, variable pharmacophoric groups that are of interest for substance P antagonist activity.
