In: Tetrahedron, 1996, vol. 52, no. 13, p. 4645-4658

While attempting to synthesize a potential inhibitor of the biosynthetic step of formation of PBG, a novel catalytic system inducing the Prins reaction was discovered. Treatment of epoxy geranial with Zn and trimethylsilyl chloride gave (1S,2S,3R,6S) 3-Chloro-3-methyl-6-isopropenyl-1,2-cyclohexanediol in high diastereoselectivity. Plus
