Asymmetric total synthesis of (+)-lycopladine A (1) has been achieved. Key elements of the synthesis include an efficient Helquist annulation to assemble the cis-fused 6/5 bicycle, Stille coupling reaction to elongate the allylic side chain, and Kröhnke pyridine synthesis to set the pyridine core at the final stage.
已实现(+)-番茄红素A(1)的不对称全合成。合成的关键元素包括有效的Helquist环组装环式6/5自行车,Stille偶联反应以延长烯丙基侧链,以及Kröhnke吡啶合成以将吡啶核心置于最后阶段。
