WebThe sporolide quinone acid is a key fragment in the biosynthesis of the complex heptacyclic marine metabolite sporolide. We report a concise enantioselective route to this fragment, which is obtained in seven steps with 65% overall yield from trimethoxybenzene. The enantioselective transfer reduction is achieved by Ipc2BCl, and the absolute … Web16 jan. 2024 · 常用名. (-)-二异松蒎基氯硼烷. 英文名. (-)-Diisopinocampheyl Chloroborane. CAS号. 85116-37-6. 分子量. 320.748. 密度.
WebThe E / Z energy differences that are observed for aliphatic ketones indicate an possible alternative explanation for the source of stereochemistry in (Ipc)2BCl reductions. If one of the two Ipc groups is much more likely to transfer a hydrogen to the carbonyl group than the other, then the enantiomeric excess of the product will be directly related to the E / Z … Diisopinocampheylborane was originally prepared by hydroboration of excess α-pinene with borane, but it is now more commonly generated from borane-methyl sulfide (BMS). The compound can be isolated as a solid. However, because it is quite sensitive to water and air, this reagent is often … Meer weergeven Diisopinocampheylborane is an organoborane that is useful for asymmetric synthesis.
