A synthesis of (S)-manoalide diol (2a) has been achieved using 2-deoxy-D-ribose as starting material to unequivocally supply the stereochemistry. Reduction of natural manoalide afforded enantiomeric manoalide diol 2b. Thus, the absolute configuration of manoalide is R (as depicted in 1).

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。

The present invention provides methods and compositions for the treatment of phospholipase-related conditions. In particular, the invention provides a method of treating insulin-related, weight-related conditions and/or cholesterol-related conditions in an animal subject. The method generally involves the administration of a non-absorbed and/or effluxed phospholipase A2 inhibitor that is localized in a gastrointestinal lumen.
