  Synthesis of dialkyl(1-allyl-3-arylprop-2-yn-1-yl)-and dialkyl(1-allyl-3-alkenylprop-2-yn-1-yl)amines by the stevens rearrangement

  摘要：

  The Stevens rearrangement of dialkyl(allyl)(3-arylprop-2-yn-1-yl)- and dialkyl(allyl)(3-alkenylprop-2-yn-1-yl)ammonium bromides gave dialkyl(1-allyl-3-arylprop-2-yn-1-yl)- and dialkyl(1-allyl-3-alkenylprop-2-yn-1-yl)amines. Here, the allyl group acts as migrating group, and 3-aryl- or 3-alkenylprop-2-yn-1-yl, as receiving one. The yields of the Stevens rearrangement products fall down as the alkyl chain becomes longer, as well as with introduction of a methyl group into the meta or para position of the aromatic ring.

  yn-2-yl)ammonium bromides under base-catalyzed condition instantly undergo intramolecular cyclization. The cyclization of dialkylpropyn-1-yl(3-isopropenylpropyn-2-yl)ammonium bromides leads to the formation of 2,2-dialkyl-5-methylisoindolinium salts. In case of allyl analogs, instead of the expected 2,2-dialkyl-6-methyl-3a,4-dihydroisoindolinium salts their isomeric forms - 2,2-dialkyl-5-methyl-2,6

  在碱催化条件下，二烷基丙炔-1-基（或烯丙基）（3-异丙烯基丙炔-2-基）溴化铵立即经历分子内环化。二烷基丙炔-1-基（3-异丙烯基丙炔-2-基）溴化铵的环化导致形成2，2-二烷基-5-甲基异吲哚鎓盐。在烯丙基类似物，而不是预期的2,2-二烷基-6-甲基- 3的情况下一个，4- dihydroisoindolinium盐及其异构体形式- 2,2-二烷基-5-甲基2,6,7,7一-获得四氢-1 H-异吲哚溴化物。在碱性介质中，它们被转化为二氢异吲哚鎓盐，其在两个方向（1,2,1,6）上的裂解导致异构的二烷基-1,4-二甲基-和2,4-二甲基苄基胺的混合物。

  Cyclization of dimethylcrotyl(3-vinyl-or-3-isopropenylpropyn-2-yl)ammonium bromides in the presence of base gave a mixture of the isomeric 2,2-dialkyl-4-methyl-and 2,2-dialkyl-4,6-dimethyl-2,6,7,7a-tetrahydro-1H-isoindolium bromides. Basic fission of the salts obtained at increased temperature gave a mixture of the isomeric N,N-disubstituted di-and trimethylbenzylamines whose structures were confirmed by their IR, H-1 NMR, and C-13 NMR spectra.
