Organo-Selenium Induced Radical Ring-Opening Intramolecular Cyclization or Electrophilic Cyclization of 2- (Arylmethylene)cyclopropylaldehyde: A Tunable Synthesis of 1-Naphthaldehydes or 3-Oxabicyclo[3.1.0]hexan-2-ols

1-Naphthaldehydes and 3-oxabicyclo[3.1.0]hexan-2-ols can be prepared, respectively, by the intramolecular alkylation and cyclization of (E)-2-(arylmethylene)cyclopropylaldehyde 1 mediated by different organo-selenium reagents. The properties of selenium reagents may play an important role in the reactions. A rationale for these transformations is proposed.
通过不同的有机硒试剂介导的(E)-2-(芳基亚甲基)环丙醛1的分子内烷基化和环化作用,可以分别制备1-萘醛和3-氧杂双环[3.1.0]己-2-醇。硒试剂的性质可能在反应中起重要作用。提出了这些转换的基本原理。
