A Rh-Catalyzed C−H Insertion Reaction for the Oxidative Conversion of Carbamates to Oxazolidinones
摘要:
Selective intramolecular alkane oxidations: an RhII carboxylate catalyzed C-H amination reaction facilitates the preparation of 1,2-amino alcohols from primary carbamates. The reaction is stereospecific, providing access to chiral α-branched amines from optically pure starting materials with no loss in enantiomeric excess.
The growth of biofilm present in open recirculating water systems is inhibited by introducing into the water comprising such a water system (a) a source of free halogen, e.g. e chlorine and (b) a source of di(lower alkyl) substituted-2-oxazolidinone, the mole ratio of (a) to (b) and the combined amount of (a) and (b) being sufficient to at least inhibit the growth of the biofilm, e.g., the bacteria comprising the biofilm, the source of free available halogen being present in less than biostatic amounts.
