The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: (S)-Methyl 3-hydroxybutanoate(SMILESS: C[C@H](O)CC(OC)=O,cas:53562-86-0) is researched.Quality Control of 2-(Thiophen-3-yl)-1,3-dioxolane. The article 《Difluorphos, an electron-poor diphosphane: A good match between electronic and steric features》 in relation to this compound, is published in Angewandte Chemie, International Edition. Let’s take a look at the latest research on this compound (cas:53562-86-0).
Both enantiomers of difluorphos I were synthesized and their stereoelectronic features were evaluated in theor. and exptl. studies. The unusual π acidity of I explains the excellent results obtained with it in ruthenium-mediated asym. hydrogenation of fluorinated β-functionalized ketones. These results are better than those obtained with other biphenyl-based diphosphines.
