Catalytic enantioselective conjunctive cross-coupling between 9-BBN borate complexes and aryl electrophiles can be accomplished with Ni salts in the presence of a chiral diamine ligand. The reactions furnish chiral 9-BBN derivatives in an enantioselective fashion and these are converted to chiral alcohols and amines, or engaged in other stereospecific C?C bond forming reactions.

Polydora websterii, a harmful lugworm that has serious adverse effects on pearl oyster cultivation, was inhibited by a marine diterpene, crenulacetal C, isolated from the brown alga Dictyota dichotoma. Based on consideration of the activity-structure relationship, several synthetic compounds having an aromatic moiety with a hydroxyalkyl chain were prepared. Bioassay using larvae of Polydora websterii as well as pearl oysters (Pinctada fucata martians) suggested that 1-(2-ferrule)-1-nonanol was the most promising inhibitor.
Transformation of Alkyl Halides to Aldehydes Having Two Additional Carbon Atoms
Shankaran, K.,Talekar, D. G.,Rao, A. S.

Methyl 3-oxo-4-phenylbutanoate (6) reacts with alkyl halides (1a-g) in the presence of NaH/benzene to furnish alkylated β-keto esters (2a-g).Hydrolysis of 2a-g gives benzyl ketones (3a-g), which on reduction with sodium borohydride give the homobenzylic alcohols (4a-g).The alcohols (4a-g) are readily fragmented to aldehydes (5a-g) on heating with lead tetraacetate/iodine.
