laccases participate in C−N bond-forming reactions through the generation of reactive nitroso intermediates from acylated hydroxylamines. The formal allylic C−H bond activation proceeds with air as the terminal oxidant and provides high yields both in intramolecular and intermolecular aminationreactions through this unprecedented biocatalytic nitroso-ene-type reaction pathway.

Short practical syntheses for five deuterium-labeled derivatives of dimethylallyl diphosphate (DMAPP) useful for enzymological studies are reported. These include the preparation of the Cl-labeled derivatives (R)-[1-H-2]3-methylbut-2-enyl diphosphate ((R)-[1-H-2]1-OPP) and (S)-[1-H-2]3-methylbut-2-enyl diphosphate ((S)-[1-H-2]1-OPP), the C2-labeled derivative [2-H-2]3-methylbut-2-enyl diphosphate ([2-H-2]1-OPP), and the methyl-labeled derivatives (E)-[4,4,4-H-2(3)]3-methylbut-2-enyl diphosphate ((E)-[4,4,4-H-2(3)]1-OPP) and (Z)-[4,4,4-H-2(3)]3-methyl-but-2-enyl diphosphate ((Z)[4,4,4-H-2(3)]1-OPP).
