Certain benzylated oxazoloisoquinolinones readily available from Reissert compounds provided an efficient access to 8-oxoprotoberberines in three steps. A series of these new precursors as well as several oxoprotoberberines were prepared and the scope and limitation of this procedure were investigated.
可从 Reissert 化合物轻松获得的某些苄基恶唑基异喹啉酮可通过 三个步骤有效地获得8-氧代小pro碱。制备了一系列这些新的前体以及几种氧代小ber碱,并研究了该方法的范围和局限性。
