In this paper we describe the synthesis of a diastereomer of the C(9)-C(20) dipropionate-lactone fragment of Calyculin C. A short and enantioselective synthesis of the key intermediate 2 has been developed. This intermediate will play a critical role also in the synthesis of the correct diastereomer of C(9)-C(20) dipropionate-lactone fragment of Calyculin C.
在本文中,我们描述了 Calyculin C 的 C(9)-C(20) 二丙酸内酯片段的非对映异构体的合成。已经开发了关键中间体 2 的短和对映选择性合成。该中间体还将在 Calyculin C 的 C(9)-C(20) 二丙酸内酯片段的正确非对映异构体的合成中发挥关键作用。
