S 98 Synthesis of a novel planar-chiral nido-carborane amino acid / A. A. Telegina, D. A. Gruzdev, G. L. Levit, V. P. Krasnov // Russian chemical bulletin. - 2021. - Vol. 70, № 3. - P539-544 Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): CARBORANE -- PLANAR CHIRALITY -- AMINO ACID -- DEBORONATION Аннотация: The deboronation of enantiomers of planar-chiral benzyl (3-formamido-1,2-dicarba-closo-dodecaboran-1-yl)acetate gave the individual (RP)- and (SP)-enantiomers (ee > 98%) of a new amino acid containing a nido-carborane fragment, (3-ammonio-7,8-dicarba-nido-undecaboran-7-yl)acetic acid. Chiral HPLC methods for the analysis of enantiomeric purity of this compound was developed. |
