Less stable, but natural: The asymmetric totalsynthesis of leucosceptroidB (see scheme) has been accomplished in 19 steps. Thermodynamically, this natural product proved to be less stable than its C11 epimer, a synthetic intermediate. This synthesis features a high degree of flexibility, facilitating its application to the preparation of a broad range of other natural derivatives.
