• Thermal cyclisation reactions of vinylogous aminomethylene Meldrum's acid derivatives
  作者：Hamish McNab、Lilian C. Monahan、Thomas Gray

  DOI：10.1039/c39870000140

  日期：——

  Flash vacuum pyrolysis of vinylogous aminomethylene derivatives of Meldrum's acid leads to new cyclisation reactions; one additional double bond results in the formation of 1H-azepin-3(2H)-ones, while two additional double bonds lead to benzamide derivatives.

  快速真空热解Meldrum酸的乙烯基氨基亚甲基衍生物会导致新的环化反应；一个另外的双键导致形成1 H -azepin-3（2 H）-one，而另外两个双键导致生成苯甲酰胺衍生物。

  作者：Zh. A. Krasnaya、E. V. Grechkina、V. S. Bogdanov

  DOI：10.1007/bf00695825

  日期：1994.2

  Reactions of animals of conjugated omega-dimethylaminoaldehydes with Meldrum's acid, N,N'-(o-phenylene)malonamides, and 2,3-dihydrophenalene-1,3-dione afford delta-dimethylaminodienones, substituted 2-dimethylamino-2H-pyrans, or oxanine salts. Cation-anionic polymethine dyes have been obtained from the latter.

  A polymer film comprising at least one compound represented by formula (I) is disclosed. A 1 and A 2 each independently represent a group having a Hammett's σp value of 0.2 or more, or bond each other to form a cyclic active methylene structure; and X 1 and X 2 each independently represent a hydrogen atom, aryl group, hetero-cyclic group, cyano, N-alkyl- or N-aryl-carbamoyl, or alkyl- or aryl-oxycarbonyl, or bond each other to form a saturated ring in which nitrogen and carbon atoms are embedded, and the group and ring may have at least one substituent.
