概要
- 論文の詳細を見る
Reaction of furazan derivatives with anethole (IV) was carried out with a view to establishing the structure-reactivity relationship of the 1,4-diaza-1,3-butadiene system. While benzofuroxan (III) reacted with IV giving 2-(p-methoxyphenyl)-3-methylquinoxaline 1,4-dioxide (VII) through 1,4-cycloaddition with loss of hydrogen, reaction of diethyl furoxandicarboxylate (XIV) with IV, contrary to expection, gave ethyl 4-methyl-5-(p-methoxyphenyl) isoxazole-3-carboxylate (XVI). In the latter case, it was thought that the formation of XVI is probably due to thermal decomposition of XIV to nitrile oxide (XV), following the addition of IV to XV and dehydrogenation.
