An efficient 1-pot procedure for the Zn-mediated redn. of nitro arenes in the presence of chloroformates leading to the corresponding N,O-bisprotected hydroxylamine is described. Reactions proceed smoothly under ambient conditions in THF-water mixts. in good to excellent yield (34-81%). Solvolysis of the bisprotected hydroxylamines with NaOMe at room temp. provides access to synthetically versatile

The present invention relates to an enzymatic composition capable of killing or inhibiting microbial cells or micro-organisms, e.g. in laundry, on hard surfaces, in water systems, on skin, on teeth or on mucous membranes. The present invention also relates to the use of said enzymatic composition for preserving food products, cosmetics, paints, coatings, etc.
The present invention relates to variants of a parent laccase. The present invention also relates to polynucleotides encoding the variant laccases and to nucleic acid constructs, vectors, and host cells comprising the polynucleotides, and methods of using the variant enzymes.
A cleaning kit comprising a cleaning agent comprising a supporting substrate and an oxidoreductase mediator. The oxidoreductase-mediator is immobilized on the supporting substrate.
A cleaning agent comprising a supporting substrate with an oxidoreductase enzyme immobilized thereon wherein the oxidoreductase enzyme is selected from oxidoreductase enzymes having an enzyme classification number selected from the group consisting of E.C. 1.1 - 1.10 and E.C. 1.12 - 1.99.
