The total synthesis and structural confirmation of the marine sponge cytotoxin (-)-irciniastatin B has been achieved via a unified strategy employing a late-stage, selective deprotection/oxidation sequence that provides access to both (+)-irciniastatin A (psymberin) and (-)-irciniastatin B.
通过采用晚期选择性保护/氧化序列的统一策略,实现了海洋海绵细胞毒素 (-)-irciniastatin B 的全合成和结构确证,该策略可同时获得 (+)-irciniastatin A(psymberin)和 (-)-irciniastatin B。
