Reactions with α-Substituted β-Propiolactones. I. 4,4-Disubstituted 2-Oxazolidinones: Research on Compounds Active on the Central Nervous System. XXIII1a
The invention relates to the novel use of bisoximes, some of which are known, for controlling unwanted microorganisms, and to processes for their preparation, and also to novel bisoximes, to processes for their preparation and to their use for controlling unwanted microorganisms and insects in crop protection and in the protection of materials.
including the particularly simple divinylglycine, which is not easily accessible by using conventional methods. A straightforwardsynthesis of symmetrically α,α-disubstituted α-amino acids is presented. The key step of this process relies on the efficient double addition of Grignard reagents to acyl cyanohydrins to provide N-acyl amino alcohols selectively in good yields. The chemoselectivity of the reaction
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.
