Synthesis of isotopically labelled versions of adenosine agonist GR79236
Autor: Derek R. Sutherland, Mark D. Wipperman, Ian Fellows, Alan H. Wadsworth, John J. Newman
Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 43:11-28
Versions of adenosine receptor agonist GR79236 (1), labelled either with carbon-14 (9) at C-8 of the purine ring or with tritium (15) in the cyclopentyl ring, were prepared in overall yields of 64% and 25% respectively. A mass labelled [M+4] version

Syntheses of isotopically labelled angiotensin II receptor antagonist GR138950X
Autor: Derek R. Sutherland, John J. Newman, Richard M. Carr, Karl M. Cable
Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 38:453-470
Syntheses of [ 13 C] and [ 14 C]-labelled versions of angiotensin II receptor antagonist GR138950X, labelled in the imidazole carboxamide residue, are described. These involved preparation of an iodoimidazole substrate by a novel iododecarboxylation

Synthesis of isotopically labelled pyridoindolone 5-HT3 receptor antagonists (1)
Autor: Lan Waterhouse, Itzela D. Correa, Shimoga R. Prakash, John J. Newman, Stephen Montgomery, Karl M. Cable, Guy N. Wells, Derek R. Sutherland, Lan Fellows
Publikováno v: Journal of Labelled Compounds and Radiopharmaceuticals. 36:993-1007
Syntheses of labelled versions of 5-HT 3 receptor antagonists, Alosetron and Lurosetron, are described. [ 14 C]Alosetron was prepared by routes utilizing either Fischer indolisation of an amidohydrazine or palladium-mediated cyclisation of an aryl en

Čerenkov Radiation from an Electron Traveling in a Circle through a Dielectric Medium
Autor: Ahmed Erteza, John J. Newman
Publikováno v: Journal of Applied Physics. 33:1864-1868
The theoretical problem of determining the Cerenkov radiation from an electron traveling in a circle through a medium has been advanced and the fields and resultant radiation from such a geometry have been determined. A solution is achieved by a tran

Ene reactions of allenes. Part 5. Regio- and stereo-selective ene reactions of a trialkylallene
Autor: Chan Boo Lee, David R. Taylor, R. John J. Newman
Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :1161
Thermal ene insertion reactions have been achieved between 2-methylpenta-2,3-diene and the reactive enophiles diethyl azodiformate, hexafluorobut-2-yne, dimethyl acetylenedicarboxylate, and 1,3-dichlorotetrafluoroacetone. In each case the ene adduct
