Structure of N,N′-bis(amino acids) in the solid state and in solution. A 13C and 15N CPMAS NMR study

(Chemical Equation Presented) Three bis(amino acids) linked by the amino groups have been prepared and structurally characterized. We have named them Gly-Gly, Ala-Ala and Gly-Ala (or Ala-Gly). These compounds have been characterized by NMR both in solution and in the solid state. They exist as zwitterions with the ammonium group proximal to the carboxylate anion. In the case of Gly-Ala, a dynamic situation is observed by CPMAS NMR (13C and 15N) corresponding to a double proton migration between two proximal tautomers.

Combination of hydrazine polyanion strategy and ring-closing metathesis in the synthesis of heterocycles

An efficient method for the synthesis of cyclic hydrazine derivatives starting from disubstituted hydrazines is reported. The method is based on the selective alkylation of hydrazine dianions with bromoalkenes and subsequent cyclization using Grubbs' cata

Ruthenium tetroxide oxidation of N,N'-Diboc hexahydropyridazines

The ruthenium tetroxide (RuO4) oxidation of the 3-substituted N,N'-diBochexahydropyridazines gave the 6-oxohexahydropyridazines in good to high yields, whereas the oxidation of the unsubstituted ones also gave the 3,6-dioxo derivatives. The 3,6

Stereospecific synthesis of cyclic hydrazoacetic acids and meso- diaminodicarboxylic acids

The hetero Diels-Alder adducts 6a - d derived from azodibenzoyl and cyclic dienes were oxidized by ruthenium tetroxide and transformed into meso- diaminodicarboxylic acids 12a - d via the new cyclic hydrazoacetic acids 9a - d.
