The ortho Claisen rearrangement of dissymmetrical, 1,4-diaryloxy-trans-2-butenes has been studied. Degradative evidence was provided to determine the migratory aptitude of the aryl moieties. An ortho substituent on the aryl ring induced greater ease of migration. Para chloro and para methyl functions induced nearly equal migratory aptitude.
已经研究了不对称的1,4-二芳氧基-反式-2-丁烯的邻克莱森重排。提供了降解性证据来确定芳基部分的迁移能力。一个邻位的芳基环上的取代基诱导更易于迁移。对氯和对甲基功能诱导了几乎相等的迁移能力。
