An H-bonding-induced radicaladdition of simple alcohols to unactivated olefins was achieved. It effectively solved the long-standing problems of reactivity and selectivity in this type of reactions. The hydroxyalkylation occurred via site-specific cleavage of the α-hydroxyl-C-H bond in alcohols. This method allows a highly atom-economic, operationally simple and environmentally benign access to diverse
The apple leaf midge and raspberry cane midge pheromones have been found to be acetoxyheptadecenone and acetoxyundecanone, respectively, and uses for the related C9-19 oxoalkyl or oxoalkenyl molecules substituted with a lower alkanoyloxy group are provided, including monitoring population levels of the midge and control of midge populations by disrupting mating patterns.

Enantioselectivebiohydrolysis of sec-alkyl sulfateesters using a bacterial alkylsulfatase from Rhodococcus ruber DSM 44541 proceeded in a stereoselective fashion though inversion of configuration. Thus, from racemic substrates, the corresponding (R)-enantiomers were hydrolyzed selectively to furnish the corresponding sec-alcohol and non-reacted sulfateester, both of (S)-configuration, which represents

Triphenylamine derivatives useful as fluorophores in biology, in particular for two-photon microscopy; and
compositions comprising these derivatives, to the use of these compositions and of the derivatives themselves for labelling biological molecules (or “biomolecules”) such as nucleic acids, oligonucleotides, proteins, polypeptides, plasmids, and the like, for their examination in particular by two-photon microscopy, and to biomolecules labelled with the said derivatives.
