Synthesis by conjugate radical addition of new heterocyclic amino acids with nucleic acid bases in their side chains
Jones,Berthelot,Iley
, p. 2131 - 2132 (2007/10/03)
N-(2-Iodoethyl) and N-(3-iodopropyl)pyrimidines and purines undergo stereoselective conjugate radical addition with an optically active oxazolidinone acceptor to give syn-adducts that can be converted into pyrimidine and purine amino acids.
Synthesis and binding behavior of an artificial receptor based on 'upper rim' functionalized calix[5]arene

, p. 12185 - 12196 (2007/10/03)
A new calix[5]arene possessing two benzoic acid moieties was synthesized as an artificial receptor and its ability of binding to a variety of amine guests was investigated. The structures of the complexes with the mines were proposed by the molecular mechanics calculation using MacroModel V. 4.0.
Heterocyclic Ambident Nucleophiles. III* The Alkylation of Sodium Adenide
Rasmussen, Malcolm,Hope, Janet M.
, p. 525 - 534 (2007/10/02)
The alkylation of sodium adenide in HCONMe2 (30 deg) with various alkylating agents was analysed by 1H n.m.r. spectroscopy.Widely varying N3:N7:N9 alkylation patterns were observed, depending on the alkylating agent.These patterns are interpreted in terms of the electrostatic, thermodynamic and steric factors involved in the different SN2 transition states appropriate to each alkylating agent.Hydrogen bonding association between the 6-amino group and certain carbonyl containing alkylating agents is proposed to explain the enhancedN7-alkylation in some cases.Support for this latter proposal was obtain from a comparison of the adenine alkylation results with the corresponding alkylation patterns of 6-pivaloylamino- and 6-chloro-purine.
