摘要:

During an investigation of the base-induced transformation of secoisopimarene 1 to gibberellin analog 2, an unexpected solvent-specific cyclization occurred generating a bicyclo[3.2.1]spirodiketone of an unexpected structure class. The structure of this interesting reaction product has been fully defined using comprehensive 2D NMR methods.
