Web1 mei 1996 · The first example of a reagent-controlled enantioselective Pictet-Spengler reaction is demonstrated. Employing diisopinocampheylchloroborane as a chiral Lewis acid catalyst, the Pictet-Spengler reaction of N b-hydroxytryptamine gave the corresponding 2-hydroxy-tetrahydro-β-carbolines up to 90 %ee. 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.
