    Acylative kinetic resolution of racemic methyl-substituted cyclic alkylamines with 2,5-dioxopyrrolidin-1-yl (R)-2-phenoxypropanoate / D. A. Gruzdev, S. A. Vakarov, M. A. Korolyova [et al.] // Organic & biomolecular chemistry. - 2022. - Vol. 20, № 4. - P862-869
Рубрики: ХИМИЧЕСКИЕ НАУКИ
Аннотация: The diastereoselective acylation of a number of racemic methyl-substituted cyclic alkylamines with active esters of 2-phenoxypropanoic acid was studied in detail. The ester of (R)-2-phenoxypropanoic acid and N-hydroxysuccinimide was found to be the most selective agent. The highest stereoselectivity was observed in the kinetic resolution of racemic 2-methylpiperidine in toluene at −40 °C (selectivity factor s = 73) with the predominant formation of (R,R)-amide (93.7% de). To explain the observed stereoselectivity, DFT modelling of the transition states in the reactions of the title acylating agent with 2-methylpiperidine and 2-methylpyrrolidine was performed. The calculated values were in good agreement with experimental data. It has been demonstrated that the acylation proceeds via a concerted mechanism, in which the addition of an amine occurs simultaneously with the elimination of the hydroxysuccinimide fragment. The high stereoselectivity of the (R,R)-amide formation is largely ensured by the lower steric hindrances in the transition states as compared to the formation of (R,S)-amide.

Аннотация: The reactions of alkyl tri-and tetrafluorosalicylates with diethylamine led to formation of the stable salts regardless of the conditions. Therein, ethyl esters were undergone dealkylation leading to formation of diethylammonium carboxylates. Methyl tetrafluorosalicylate was subject to similar transformations, while trifluoro-containing analog gave salt at the hydroxyl group and in which ester fragment was remained.
