| titleOfInvention | Process for producing 2-isocyanato-2,3-dehydro carboxylic esters |
| abstract | ABSTRACT OF THE DISCLOSURE 2-isocyanato-2,3-dehydrocarboxylic acid esters having the general formula wherein R1 represents a straight-chain or branched (C1-C4)alkyl radical, a phenyl radical or a benzyl radical, and R2 represents hydrogen or a methyl radical and R3 represents a straight-chain or branched (C1-C16)alkyl radical, a (C3-C8)cycloalkyl radical, a (C1-C6)alkyl-mercapto radical or a phenyl radical, are pro-duced by reacting 2-azido-carboxylic acid esters having the general formula (II) in an inert solvent at a temperature of between 0 and 150°C in the presence of a perrhenate with phosgene or diphosgene. The compounds having the general formula (I) can be converted with benzyl alcohol or with tert-butyl alcohol into the correspond-ing 2- and BOC-protected 2,3-dehydro-2-aminocarboxylic acid esters, which are in turn valuable components for the synthesis of dehydro peptides. |
