We have synthesized and isolated two C2-symmetric enantiomerically pure trisadducts of C60 with an inherently chiral trans-3,trans-3,trans-3 addition pattern with the aid of an enantiopure cyclo-tris-malonate tether. An unexpected stereoisomerism was observed which was attributed to the spatial arrangement of spacers in the tether.
B y now you should be familiar with position isomers wherein compounds of the same molecular formula differ because substituents, chain branches, and so on, are not at the same positions in the molecules. 1-Chloropropane and 2-chloropropane are straightforward examples of position isomers. A much more subtle form of isomerism is present when two dijfjrerent compounds have the same molecular for...
Oxaliplatin is successfully used in systemic cancer therapy. However, resistance development and severe adverse effects are limiting factors for curative cancer treatment with oxaliplatin. The purpose of this study was to comparatively investigate in vitro and in vivo anticancer properties as well as the adverse effects of two methyl-substituted enantiomerically pure oxaliplatin analogs [[(1R,2...
Graph kernels provides a framework combining machine learning and graph theory. However, kernels based upon the molecular graph, which can not distinguish stereoisomers, are unable to predict properties which differs among stereoisomers. This article presents a graph kernel which takes into account chirality, and is used (in combination with a classical graph kernel) to predict the optical rota...
