Potential-energy calculations of terminally blocked tetrapeptides from the third loop of short-chain snake venom neurotoxins

Autor: H. Marita Roos, Petrus H. van Rooyen

Publikováno v: International Journal of Peptide and Protein Research. 44:562-567

The conformational space of six tetrapeptides from the β-bends in the third loop of short-chain snake venom neurotoxins was investigated with the aid of energy calculations. It was shown that these peptides can be divided into two groups: those with

Phosphonic systems Part 9. Solution and solid state structure of R,R (S,S) stereoisomers of the adducts of diethyl(1-cyclohexenyl)methylphosphonate and aldehydes

Autor: Kobus P. Gerber, Tomasz A. Modro, H. Marita Roos

Publikováno v: Journal of Molecular Structure. 296:85-93

The solution and solid state structures of single stereoisomers of α-adducts of diethyl(1-cyclohexenyl)methyl-phosphonate and three aldehydes were determined by NMR spectroscopy and by X-ray diffraction. In both phases, the molecules exist in virtua

Insertion of iron carbonyl into a CS bond of tetrathiofulvalene

Autor: Helgard G. Raubenheimer, H. Marita Roos, Lorna Linford

Publikováno v: Journal of Organometallic Chemistry. 393:C49-C52

Irradiation of a mixture of tetrathiofulvalene (TTF) and iron pentacarbonyl in THF gives a dinuclear hexacarbonyl iron chelate, Fe2(CO)6[μ-SC( CSCHCHS )SCHCH] (1), by ring-opening of TTF adjacent to an internal double bond. The donated liga
