Mass-spectral behavior and thermal stability of hetaryl analogs of unsymmetrical benzoins

The main path in the mass-spectral dissociation of the hetaryl analogs of unsymmetrical benzoins is β-fragmentation with cleavage of the central C-C bond. Here, the strongest peak in the mass spectra of α-benzoins is the peak of the hydroxymethylhetaryl cation, and in β-benzoins it is the peak of the hetaroyl cation. The thermal α → β isomerization of the hetaryl analogs of benzoin was studied. In the case of indole and pyrrole derivatives the formation of polyheterocyclic systems is observed. 2006 Springer Science+Business Media, Inc.

Interaction of N,N-dimethyl-hydrazonomethyl and α-hydroxyketone groups in hetaryl analogs of unsymmetrical benzoins

The reaction of phenylglyoxal hydrate with N,N-dimethylhydrazones of furfural and 1-methylpyrrole-2-carbaldehyde proceeds regioselectively at position 5 of the heterocycle. The hetaryl analogs of α-benzoins obtained are quantitatively isomerized into the

Mutual influence of (dimethylhydrazono)methyl groups and α-hydroxy ketone moieties in hetaryl analogues of unsymmetric benzoins

Reactions between phenylglyoxal hydrate and the N,N-dimethylhydrazones of furfural and pyrrole-2-carbaldehyde run regioselectively at the 5-position of the heterocycle. The resulting hetaryl analogues of α-benzoins quantitatively isomerize to β-compounds,
