Abstract

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 α,β-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.
