Latest Patents

Yuji Urabe holds a patent for a unique chemical process involving 5-trihalogenomethyl-4,5-dihydro-oxazole-4-carboxylic acid esters. This invention describes a method where alkyl (or aralkyl) α-isocyanoacetate is condensed with a trihalogenoacetic aldehyde or its hydrate in the presence of an amine. The result is the formation of trans-4-alkoxycarbonyl (or aralkyloxycarbonyl)-5-trihalogenomethyl-2-oxazoline. This oxazoline compound can be hydrolyzed under acidic conditions to yield threo-γ,γ,γ-trihalogenothreonine, which can then undergo catalytic or electrolytic reduction. Notably, these reactions can be performed stereoselectively, allowing for the production of threo-threonine without by-products such as allo-threonine.
