Treatment of tertiary alcohols and trisubstituted olefins of the tetrahydronaphthalene series with the HN3H2SO4 reagent leads directly and with good yields to a new class of compounds: the 3,4-dihydro 5H benzo (b) azepins substituted on position -2. The latter, on reduction, give the corresponding 2,3,4,5-tetrahydro 1H benzo (b) azepins, most of them being unknown in the literature. This work shows
四氢萘系列与HN的叔醇和三取代的烯烃的治疗3 H 2 SO 4试剂引线直接和具有良好产率的新的一类化合物:3,4-二氢苯并5H(b)中azepins取代的位置上- 2。后者在还原时得到相应的2,3,4,5-四氢1H苯并(b)氮杂环庚烷,其中大多数在文献中是未知的。这项工作表明该环膨胀反应具有很高的区域特异性,这可以用电子和空间效应来解释。
