  • Process for preparing 8,12-epoxy-13,14,15,16-tetranorlabdane
    Patent number: 4503240
    Abstract: Process for the preparation of 8,12-epoxy-13,14,15,16-tetranorlabdane by way of converting farnesyl bromide to farnesyl cyanide, followed by the saponification of the farnesyl cyanide to homofarnesic acid which is then cyclized to norambreinolide in the presence of titanium tetrachloride, converting the norambreinolide with LiAlH.sub.4 to 8-hydroxy-13,14,15,16-tetranorlabdane-12-ol, and cyclization of the diol in the presence of POCl.sub.3 to 8,12-epoxy-13,14,15,16-tetranorlabdane. The resulting product exhibits an amber scent, used in perfumery.
