enantioselective total synthesis of (-)-spongidepsin (2) and elucidation of the absolute stereochemistry of its four stereocenters are described. Spongidepsin (2), a 13-membered depsipeptide isolated from the Vanuatu marine sponge Spongia sp., has shown potent antitumor properties against a variety of NCI tumor cell lines. Our synthesis is convergent, and the absolute stereochemistry of four of the five
[结构:见正文]描述了对映体选择性合成(-)-海绵蛋白酶(2)以及阐明其四个立体中心的绝对立体化学。海绵肽(2)是一种从Vanuatu海洋海绵Spongia sp。分离的13元的十肽,已显示出对多种NCI肿瘤细胞系的有效抗肿瘤特性。我们的合成是收敛的,并且五个手性中心中的四个的绝对立体化学是通过合成指定的。
