• Pyrolytic Methods in Organic Synthesis: Novel Routes for the Synthesis of 3-Oxoalkanenitriles, 2-Acyl Anilines, and 2-Aroyl Anilines

  3-Oxoalkanenitriles 1a-d were obtained in high yield by treating enaminones 6a-d with hydroxylamine hydrochloride and stirring the resulting oxime with diethyl oxalate. The formed 3-oxoalkanenitriles 1a,b readily undergo self-condensation to yield 2-aroylanilines 3a,b on heating in pyridine for eight hours or by irradiation in microwave for 1.5 minutes. In contrast, 1c-e were recovered unreacted under similar conditions. Pyrolysis of 3-aminocrotononitrile 14 produced a mixture of the aminopyridine 16, 19, and aminobenzene 22. Heating 14 in aqueous media has resulted in formation of the pyridine 20, while heating the same compound in acetic acid has afforded pyridone 20 and acetyl pyridine 24.

  3-氧代烷腈1a-d通过将烯胺酮6a-d与盐酸羟胺反应，并将生成的肟与乙二酸二乙酯搅拌而获得，产率很高。形成的3-氧代烷腈1a,b在吡啶中加热8小时或在微波中照射1.5分钟后，容易发生自缩合反应，生成2-芳酰氨基苯3a,b。相反，1c-e在类似条件下未反应而被回收。3-氨基克罗顿腈14的热解产生了氨基吡啶16、19和氨基苯22的混合物。在水相中加热14导致生成吡啶20，而在醋酸中加热同一化合物则生成吡啶酮20和乙酰吡啶24。

  The reaction of ‘push–pull’ enamines with trifluoromethyl-containing 1,3-dicarbonyl compounds was investigated. It was found that the reaction is sensitive both to the structure of the enamines and to reaction conditions. As a result, a set of various trifluoromethyldialkylanilines was obtained.
