    Abstract: The nucleophilic displacements at carbonyl center are remarkable. Mainly stepwise mechanism was found in these reactions. The stepwise mechanism with rate-limiting addition of the nucleophilie to the carbonyl group to form zwitterionic tetrahedral intermediate was a common type of mechanism. Such as, Dey et al. [1] proposed the pyridinolyses of α-c... Show More

    Abstract: The synthesis of myristicin ketone from myristicin has been achieved through conversion of allyl group to ketone. Myristicin was isolated from nutmeg oil. The reaction of myristicin with mercury acetate in aqueous tetrahydrofuran, followed by in situ reduction of the mercurial intermediate by alkaline solution sodium borohydride produced myristicin...
