Total Synthesis of (+/-)-Batzelladine K: A Biomimetic Approach

[摘要]：Total synthesis of batzelladine K was achieved by a biomimetic approach. The key reactions involve two Wittig reactions of phosphoranes and aldehydes leading to an alpha,beta-unsaturated ketone, followed by a condensation with guanidine. The synthesis was accomplished in four steps with an overall yield of 12%. The relative stereochemistry of batzelladine K was established by NOE experiments and comparison with literature values.
