An elegant synthesis of ophiocerins B and C is accomplished for the first time with 3 R,4 R,6 R and 3 S,4 S,6 R-configuration. Of these three stereogenic centers, the C-3/C-4 VIC-diol was created by Sharpless asymmetric dihydroxylation, while the C-6 stereocenter was achieved from known chiral epoxide. The synthesis of ophiocerins B and C defined the absolute stereochemistry of these natural products
首次以 3 R,4 R,6 R 和 3 S,4 S,6 R 构型完成了 ophiocerins B 和 C 的优雅合成。在这三个立体中心中,C-3/C-4 VIC-二醇是通过 Sharpless 不对称二羟基化产生的,而 C-6 立体中心是由已知的手性环氧化物制成的。ophiocerins B 和 C 的合成定义了这些天然产物的绝对立体化学。
