  Establishment of Benzodioxazine Core Structure for Sarcodonin Class of Natural Products by X-ray Analysis

  摘要：

  Sarcodonin epsilon (2), isolated from Sarcodon scabrosus, was treated with trimethylsilyldiazomethane to yield a crystalline methylated derivative 6. The structure of 6 was determined by X-ray analysis, which confirmed the presence of an unprecedented N(1b)-OMe group, the configuration at N(1b) and the 1,3,4-substituted phenyl ring structure of 2. More importantly, the structures of 6 and 2 have answered the intriguing problem of solving the core structure of the sarcodonin class of natural products, establishing that sarcodonins have a benzodioxazine core structure, rather than the recently proposed benzodioxane aminal core structure.
