organic chemistry, reviewHoveyda–Grubbs catalyst has been successfully fine-tuned by us in order to increase its activity and applicability by the introduction of electron-withdrawing groups (EWGs) to diminish donor properties of the oxygen atom. As a result, the stable and easily accessible nitro...

We describe our studies concerning successive nucleophilic vinylic substitution reactions of dinitrobuta-1,3-diene in order to establish the reactivity profile of this precursor and determine whether this precursor could be used for the synthesis of many dinitrodiene analogues offering new methodology ...
Treatment of cyanamide with tetrazine-3,6-dicarboxylate led to a 5-amino-1,2,4-triazine derivative, which was rearranged to 4-aminoimidazole-2,5-dicarboxylic acid dimethyl ester.Muller JTroschutz RSynthesis: International Journal of Methods in Synthetic Organic Chemistry...
