Vorschrift

The same synthesis as that carried out in the case of Example 11, from (+)-(1,2,3,4,4a,9b-hexahydro-1,4a,9b-trimethyl-1,4-methanodibenzofuran-8-yl)carboxylic acid, followed by hydrogenation under the same conditions as in Example 21, results in the laevorotatory enantiomer 13 exhibiting the same physicochemical characteristics as those of the enantiomer 12; αD =-3.2° (c=1, CHCl3).
