  The total synthesis of renierone, mimocin, renierol, renierol acetate, renierol propionate, and 7-methoxy-1,6-dimethylisoquinoline-5,8-dione was successfully achieved by the regioselective oxidation of 5-oxygenated isoquinoline. The synthetic method of the 5-oxygenated isoquinoline is based on the thermal electrocyclic reaction of 1-azahexatriene system involving the benzene 1,2-bond.

  日期：1997.8

  A new six-step synthetic route for the preparation of the alkaloid from marine origin, 5,8-dihydro-7-methoxy-1,6-dimeethylisoquinoline-5,8-dione is reported. The method is based on the electrocyclization of the appropriate β-arylvinyl ketenimine, available by aza Wittig reaction of the corresponding vinyl iminophosphorane with (trimethylsilyl)ethenone followed by decarboxylation and further oxidative demethylation. Likewise, this method has successfully been applied to the preparation of the 3-ethoxycarbonylrenierol.
