Manoalide, an analgesic and anti-inflammatory sesterterpene, has been stereoselectively synthesized for the first time. The C-4 stereogenic centre has been introduced in an early step by enantioselective aldol condensation using a Ti(OiPr)4/(R)-(+)-binol complex.
Manoalide是一种止痛和消炎性的酯基萜烯,是首次立体选择性地合成的。C-4立体生成中心已通过使用Ti(O i Pr)4 /(R)-(+)-二元醇复合物的对映选择性羟醛缩合在较早的阶段引入。
