Aminolysis of methoxy groups in pyrimidine derivatives. Activation by 5-nitroso
Autor: Group M. Melguizo, A. Marchal, M. Nogueras, A. Sánchez, J. N. Low
Publikováno v: Journal of Heterocyclic Chemistry. 39:97-103
The nucleophilic substitution of 2-mefhoxy groups in pyrimidine derivatives was strongly activated by introduction of a 5-nitroso group on to the pyrimidine ring. The aminolysis of several 2-methoxy-5-nitrosopyrimidine derivatives was performed at ro

Autor: C. J. Breheny, Conor Long, S. M. Draper, J. J. Byrne, J. N. Low
Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 50:1669-1671
The molecular structure of tricarbonyl(η 6 -pyridine)chromium(0), [Cr(CO) 3 (C 5 H 5 N)], is presented here. The Cr atom is bound to the pyridine ring via the π-electron system and is situated directly below the heteroarene ring centre. The pyridin

Correlation between glycosyl torsion angle and sugar ring pucker does not always exist
Autor: P. Tollin, H.R. Wilson, J. N. Low
Publikováno v: Nucleic Acids Research. 10:5599-5604
A survey of the conformational parameters of deoxypyrimidine nucleosides and nucleotides shows that the correlation between glycosyl torsion angle and sugar pucker, which has often been considered to be well-established, does not always exist. This m
