Заглавие : Synthesis of N-[(3-Amino-1,2-dicarba-closo-dodecaboran-1-yl)acetyl] Derivatives of alfa-Amino Acids Место публикации : Collection of Czechoslovak Chemical Communications. - 2007. - Vol. 72, № 12. - С. 1697-1706 ББК : 54 Предметные рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The N-[(3-amino-1,2-dicarba-closo-dodecaboran-1-yl)acetyl] derivatives of amino acids were prepared starting from N-protected (Ac, Form, Bz, and Boc) 3-amino-1-(carboxymethyl)-o-carboranes and alkyl esters of natural amino acids using the carbodiimide method of coupling and removing the ester groups. All the amides obtained were diastereoisomeric mixtures. Some diastereoisomers were separated and the assignment of the absolute configuration of aminocarborane fragments was performed by X-ray crystallography Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Levit, G.
