It has been shown that acidic hydrolysis of diastereomeric amides of 1-methyl-3-amino-1,2-dicarba-closo-dodecaborane results in the partial racemization of the target 3-amino-1-methylcarborane. Under the similar conditions, the hydrolysis of N-acyl-3-amino-1-phenyl-1,2-dicarba-closo-dodecaboranes resulted in amide bond cleavage accompanied by simultaneous deboronation with the removal of boron atom at position 6 of carborane cage and formation of 7,8-dicarba-nido-undecaborane derivative according to 11B and 1H NMR spectroscopy. \\\\Expert2\\nbo\\Journal of Organometallic Chemistry\\2005, v. 690, p.2783.pdf |

Isomeric lactams, that is, (2S,4S)-4-arylamino-5-oxoprolines, can be easily converted in acidic medium into more stable 4-amino-1-aryl-5-oxoprolines. |

Kodess // European Journal of Organic Chemistry. - 2007. - № 25. - P4257-4266 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: The possibility of obtaining the stereoisomeric derivatives of 5-oxoproline and glutamic acid with a tertiary amino group at C-4, using the nucleophilic substitution of bromine in dimethyl (2S,4RS)-4-bromo-N-phthaloylglutamate with secondary amines followed by resolution of diastereomers and removal of protecting groups has been studied. We have shown that the reaction with arylamines results in optically pure 5-oxoproline derivatives in high yields. In the case of more basic amines, the reaction is accompanied by racemization, and the target products can be isolated only as diastereomeric racemates. |
