The first synthesis of clavatadine C was achieved in 5 steps and an overall yield of 38%. The key step in the synthesis features a highly efficient one-pot dibromination and oxidative spirocyclization sequence to forge the spiro-2,6-dibromocyclohexadienone isoxazoline scaffold. Clavatadine C was found to possess moderate cytotoxicity against both breast and colon cancer cell lines.
克拉维他定C的第一次合成分5步完成,总收率为38%。合成的关键步骤是高效的一锅二溴化和氧化螺环化序列,以打造螺-2,6-二溴环己二酮异恶唑啉骨架。发现克拉维他汀C对乳腺癌和结肠癌细胞系均具有中等细胞毒性。
