The sex pheromone of Matsucoccus matsumurae Japanese pine bast scale (2E,4E)-(6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one (1) was synthesized with stereocontrol from (2R,4S)-5-acetoxy-2,4-dimethyl-pentanol (3), which in turn was prepared by lipase-catalyzed transesterification of meso-2,4-dimethyl-1,5-propanediol (2).

A new synthesis of (2E,4E,6R,10R)-4,6,10,12-tetramethyl-2,4-tridecadien-7-one (1; matsuone) was achieved by starting from (2R,3S)-4-(tert-butyldiphenylsilyloxy)-2,3-epoxy-1-butanol (21 = E) and methyl (R)-3-hydroxy-2-methylpropanoate (2 = I).Cleavage of 2

North American beavers (Castor canadensis) mark their territories with castoreum, the strong-smelling paste in their castor sacs. In their own territories, beavers respond with scent marking to experimental scent marks that consist of strange castoreum (or selected components). In part, the unique odor of castoreum is due to large amounts of phenolic compounds and neutral compounds. Purified neutral compounds were analyzed by GC, GC-MS, and NMR; identities of the neutral compounds were confirmed by comparing the properties of authentic compounds with those of the isolated compounds. We identified 13 neutral compounds that had not been reported before for castoreum. Most of these are oxygen-containing monoterpens. Of the nine neutral compounds reported by Lederer (1949), only three are confirmed in our analysis; the other six neutral compounds are either absent or are not volatile enough to be detected by our methods. Eight compounds - 6-methyl-1-heptanol, 4,6-dimethyl-1-heptanol, isopinocamphone, pinocamphone, two linalool oxides, and their acetates - were synthesized for structure identification and bioassays.

The hydroalumination of a series of alkenes and some fused aromatic hydrocarbons by the LiAlH4*3AlBr3 system in low-polar solvents was studied.Alkenes with mono-, di-, tri-, and tetraalkyl substituted, mono- and diaryl substituted double bonds and anthracene react at room temperature to give the corresponding dibromoaluminoalkanes in high yields.Benzylidenefluorene, tetraphenylethylene, naphthalene, and phenanthrene do not undergo hydroalumination under these conditions.Camphene, bicyclooct-2-ene, and norbornene afford the corresponding organoaluminum compounds with high stereoselectivity.Oxidation and halo- and acyldemetallation of the resulting alkyl- and arylalanes were carried out.
