  A [4+2]-cycloaddition of quinazoline (2) and the 3H-1, 2, 3-triazolo[4, 5-d]pyrimidine 4 with enamines 1a-e resulted in ring transformation into the quinolines, 3a and 3c, and the 3H-1, 2, 3-triazolo[4, 5-b]pyridines, 5a-e, respectively. Similarly, the ynamine 13a cycloadded to 2 and its 4-cyano derivative 6, giving the quinolines, 14a and 14b, respectively.On the other hand, the 3H-1, 2, 3-triazolo[4, 5-d]pyrimidines 4, 15, 8, 16, 17, 18, and 19 underwent [2+2]-cycloaddition with the ynamine 13a, resulting in ring transformation into the corresponding 3H-1, 2, 3-triazolo[4, 5-d]-[1, 3]diazocines 21a-27. The 7-methoxy derivative 20, the 4-methoxy- and 4-cyano-1H-pyrazolo[3, 4-d]pyrimidines, 30 and 31, and the 6-cyano-9H-purine 36 also underwent [2+2]-cycloaddition with 13a to give the corresponding 3H-1, 2-3-triazolo[4, 5-b][1, 5]diazocine 28, 1H-pyrazolo[3, 4-b][1, 5]diazocines, 32 and 33, and 3H-imidazo[4, 5-b]-[1, 5]diazocine 37, respectively.The structures of the 1, 3- and 1, 5-diazocines, 21a and 28, were determined by X-ray crystallography.

  喹唑啉（2）和3H-1, 2, 3-三氮杂[4, 5-d]嘧啶（4）与烯胺（1a-e）进行[4+2]环加成反应，导致环转化为喹啉（3a和3c）和相应的3H-1, 2, 3-三氮杂[4, 5-b]吡啶（5a-e）。类似地，烯氨（13a）与2及其4-氰基衍生物6进行环加成，分别生成喹啉（14a和14b）。另一方面，3H-1, 2, 3-三氮杂[4, 5-d]嘧啶（4、15、8、16、17、18和19）与烯氨（13a）发生[2+2]环加成反应，导致环转化为相应的3H-1, 2, 3-三氮杂[4, 5-d]-[1, 3]二氮环（21a-27）。7-甲氧基衍生物20、4-甲氧基和4-氰基的1H-吡唑[3, 4-d]嘧啶（30和31）以及6-氰基-9H-嘌呤（36）也与13a发生[2+2]环加成，分别生成相应的3H-1, 2-3-三氮杂[4, 5-b][1, 5]二氮环（28）、1H-吡唑[3, 4-b][1, 5]二氮环（32和33）和3H-咪唑[4, 5-b]-[1, 5]二氮环（37）。1, 3-和1, 5-二氮环（21a和28）的结构通过X射线晶体学确定。

  The 1-substituted phthalazines 6 underwent inverse-electron-demand Diels-Alder reaction with the enamines 3 and ynamines 9, resulting in the formation of 1-substituted naphthalenes.Thus, 1-phthalazinecarbonitrile (6b) reacted with 3a-i to give the corresponding 1-naphthonitriles 7a-e, g, h and 2, 3-kihydro-1-naphthonitriles 8f, i, respectively. Similarly, reaction of 1-(methylsulfonyl)phthalazine (6c) with 3a, b, d, f gave the corresponding 1-(methylsulfonyl)naphthalenes 10a, b, d and 1-(methylsulfonyl)-2, 3-dihydronaphthalene 11f. Furthermore, 1-methylthio- (6e), 1-phenyl- (6f), 1-methyl-(6b), 1-chlorophthalazines (6h) and phthalazine (6a) reacted with 3a to afford the corresponding 4-substituted 2, 3-dihydro-1H-benz[f]indenes 12e-h, a, respectively.A similar ring transformation was found to proceed between 1, 4-phthalazinedicarbonitrile (14) and 1-methyl-1H-indole (13), giving the benzo[b]carbazoledicarbonitrile (15).Compounds 6b and 6c also underwent inverse-electron-demand Diels-Alder reaction with the ynamines 9a, b to give the corresponding 1-cyano-16a, b and 1-(methylsulfonyl)naphthalenes 17a, b, respectively.

  因此，1-酞嗪甲腈（6b）与 3a-i 反应，分别得到相应的 1-萘甲腈 7a-e、g、h 和 2、3-基氢-1-萘甲腈 8f、i。同样，1-（甲磺酰基）酞嗪（6c）与 3a、b、d、f 反应，得到相应的 1-（甲磺酰基）萘 10a、b、d 和 1-（甲磺酰基）-2，3-二氢萘 11f。此外，1-甲硫基（6e）、1-苯基（6f）、1-甲基（6b）、1-氯酞嗪（6h）和酞嗪（6a）与 3a 反应，分别得到相应的 4-取代的 2，3-二氢-1H-苯并[f]茚 12e-h、a。化合物 6b 和 6c 还与亚萘胺 9a 和 b 发生了反电子需求的 Diels-Alder 反应，分别得到了相应的 1-氰基-16a、b 和 1-（甲磺酰基）萘 17a、b。

  Acid chlorides, phosgene, thiophosgene, thionyl chloride and aromatic sulfonyl chlorides readily add to ynamines to give α-chloro-enamines. The α-chloro-β-chlorocarbonyl-enamines (V) are thermally remarkably stable as illustrated by their distillation in vacuum without decomposition. The reaction of ynamines with oxalyl chloride led to 5-disubsituted amino-2,2-dichloro-3 (2H)-furanones (XIX)

  酰氯，光气，硫光气，亚硫酰氯和芳族磺酰氯很容易加到ynamines中，得到α-氯-enamines。α-氯-β-氯羰基-烯胺（V）具有热稳定性，如在真空中蒸馏而未分解所示。乙胺与草酰氯的反应生成5-二取代的氨基-2,2-二氯-3（2H）-呋喃酮（XIX）

  1-Chlorophthalazine reacts with two molar of ynamines to give penta-substituted pyridine derivatives by N-N bond cleavage of phthalazine ring. We realize this is common to other halo-substituted condensed pyridazines.

  1-Chlorophthalazine 与两摩尔的 ynamines 反应，通过酞嗪环的 N-N 键裂解生成五取代吡啶衍生物。我们意识到这一现象与其他卤代缩合哒嗪很相似。
