Giordano, Claudio; Coppi, Laura published the artcile< Br3- vs Br2: opposite diastereoselectivity in the bromination of enantiomerically pure ketals>, HPLC of Formula: 112-63-0, the main research area is stereochem bromination ketal bromine onium tribromide.
For the first time it has been shown that different halogenating species (Br3- vs. Br2, SO2Cl2 and ICl) provide opposite high diastereofacial selectivity in the functionalization of chiral auxiliary bound alkenes. The stereochem. outcome of the bromination of ketal I (n = 1; R = H), precursor of a single geometry constrained enol ether I (n = 0), with Br3- in different solvents is reported and compared with that with Br2. Thus, up to 99% of I (R = Br) was obtained in the bromination of I (R = H) with tetraalkylammonium tribromides, while the diastereomeric product was formed in up to 99% yield, when I (R = H) was brominated with Br2 in THF.
Journal of Organic Chemistry published new progress about Bromination, stereoselective. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, HPLC of Formula: 112-63-0.
