摘要
Phakellistatin 13 is a good antitumor lead compound isolated from halobios. It was synthesized first time by solution method in combination of stepwise coupling and segment condensation. Final deprotection and cyclization were achieved according to our designed method, which was different from the reported process. The spectral data of synthetic product is consisted with literatureal data of natural product. Total synthesis of phakellistatin 13 is a significant achievement to further study of its derivatives and developing novel antitumor drugs.
