Regioselective reductive opening of 2,3-epoxy alcohol derivatives with lithium borohydride in a solid state
摘要:
2, 3-Epoxy alcohol derivatives were reduced regiospecifically with lithium borohydride in a solid state suspended in hexane to yield the corresponding C-3 opening products.

nucleophile. In this mechanistic context, complexes that contain multiple metal centers in appropriate relative proximity and orientation can provide improved reactivity relative to monometallic catalysts. For example, chiral metal salencomplexes such as 1 are effective catalysts for asymmetric epoxide ringopening reactions, and operate by a second-order mechanism.2 Linking these catalysts as dimers3 or to

Co(III)salencatalysts is reported. Olefin metathesis has been used as a key construction tool for the multimetallic structures starting from versatile allyl-substituted salen scaffolds. The Co(III) complexes were tested in the hydrolytickineticresolution of (rac)-1,2-epoxyhexane and epoxide ring opening reactions using methanol as the nucleophile. The preliminary results suggest a cooperative mode
