The biosynthesis of 2-methylisoborneol was reconstituted by elongation of dimethylallyl diphosphate (DMAPP) with (S)- and (R)-2-methylisopentenyl diphosphate (2-Me-IPP) using farnesyl diphosphate synthase (FPPS), followed by terpene cyclisation. The stereochemicalcourse of the FPPS reaction was studied in detail using stereoselectively deuterated 2-Me-IPP isotopomers.
2-甲基异冰片的生物合成通过使用法尼基二磷酸合酶 (FPPS) 用 ( S )- 和 ( R )-2-甲基异戊烯基二磷酸 (2-Me-IPP)延伸二甲基烯丙基二磷酸 (DMAPP) 进行重组,然后进行萜烯环化。使用立体选择性氘代 2-Me-IPP 同位素对 FPPS 反应的立体化学过程进行了详细研究。

A new method for the construction of steroid sidechains through the addition of lithium salts of dithianes to a C-22 aldehyde was developed. An efficient one-pot procedure for the preparation of a suitable C-22 aldehyde from commercial epibrassinolide in three steps in 86% isolated yield was described. Enantioselective hydroxymethylation of isovaleraldehyde and Kulinkovich cyclopropanation of silylated
