In an article, author is Meyer, Stephanie, once mentioned the application of 4254-14-2, Name is (R)-Propane-1,2-diol, molecular formula is C3H8O2, molecular weight is 76.0944, MDL number is MFCD00066248, category is chiral-catalyst. Now introduce a scientific discovery about this category, Product Details of 4254-14-2.
An I(I)/(III) catalysis strategy to construct an enantioenriched fluorinated isostere of the Pr-i group is reported. The difluorination of readily accessible alpha-CF3-styrenes is enabled by the in situ generation of a chiral ArIF2 species to forge a stereocentre with the substituents F, CH2F and CF3 (up to 95 %, >20:1 vicinal:geminal difluorination). The replacement of the metabolically labile benzylic proton results in a highly preorganised scaffold as was determined by X-ray crystallography (pi ->sigma* and stereoelectronic gauche sigma ->sigma* interactions). A process of catalyst editing is disclosed in which preliminary validation of enantioselectivity is placed on a structural foundation.
