A simple, inexpensive, step economic, and highly modular synthetic strategy to access izidine alkaloids is described. The key step is a TfOH-promoted intramolecular aldol condensation between enol and cyclic imide moieties. This cyclization strategy

A thermal protocol is reported for the formal insertion of nitric acid into aryldiazoacetates using Fe(NO3)3·9H2O. This strategy is mild and high yielding and allows the preparation of a large vari...

The reaction of ninhydrin with amines leads to the formation of Ruhemann’s purple. This study presents the synthesis of Ruhemann’s purple and a new benzo-fused spiroheterocyclic system by the reaction between ninhydrin and phenylethylamine. The s

The influence of hydroxyl groups on the β-phenylethylamine aromatic ring was studied during its reaction with non-enolizable aldehydes. Computational calculations established that the degree of hydroxylation generates differences in the activation p

Through analysis of 1H NMR spectra, evidence was found for intermolecular interactions between macrocyclic amino acid derivatives from L -tyrosine and their importance in the formation of aggregates in solution. It was also shown that both macrocycli
