Vitamin B12-catalyzed allylic dimerization of some γ- and δ-bromoalkanols with activated Zn-dust in mixture ethanol/water (1:1) has been studied. Investigated bromoalkanols were prepared from corresponding tertiary Δ4- and Δ5-alkenols by means of benzeneselenyl bromide and subjected to chemical reduction with vitamin B12. All investigated bromoalkanols, after dehydrobromination, underwent to oxidative allylic coupling and hydratation in the presence of protic solvents to give predominantly polyhydroxy alkanols. 相似文献
