  • N-Tosyl-(S)-Prolyl Chloride in Kinetic Resolution of Racemic Heterocyclic Amines
    作者:D. A. Gruzdev、S. A. Vakarov、G. L. Levit、V. P. Krasnov

    日期:2014.3
    The kinetic resolution of racemic heterocyclic amines via acylation with N-tosyl-(S)-prolyl chloride was systematically investigated. It was established that racemic mixtures of aromatic amines could be resolved with high efficiency, while the acylation of 2- and 3-methylpiperidines occurred with low diastereoselectivity. A method for the preparation of enantiomerically pure (3R)-7,8-difluoro-3-methyl-3
    系统研究了外消旋杂环胺经N-甲苯磺酰基-(S)-脯氨酰氯酰化的动力学拆分。已经确定,芳族胺的外消旋混合物可以高效分离,而2-和3-甲基哌啶的酰化则以低的非对映选择性发生。开发了制备对映体纯的(3 R)-7,8-二氟-3-甲基-3,4-二氢-2 H- [1,4]苯并恶嗪的方法。

    The acylative kinetic resolution of racemic heterocyclic amines such as 3,4-dihydro-3-methyl-2H-[1,4] benzoxazines, 3,4-dihydro-3-methyl-2H-[1,4]benzothiazine, 2-methyl-1,2,3,4-tetrahydro-quinolines and 2-methylindoline with enantiopure (R)-2-phenoxypropionyl chloride has been studied. It has been found that acylation of 3,4-dihydro-3-methyl-2H-[1,4]benzothiazine proceeds with the best stereoselectively when compared with other racemic amines. An efficient method for the preparation of (S)-3,4-dihydro-3-methyl-2H-[1,4]benzothiazine (99.4% ee) via a kinetic resolution protocol was developed. The possibility of recycling (R)-2-phenoxypropionic acid has been demonstrated. (C) 2016 Elsevier Ltd. All rights reserved.

    Novel conjugates of purine and 2-aminopurine linked with heterocyclic amines, including chiral derivatives of 3,4-dihydro-2H-[1,4]benzoxazine, 3,4-dihydro-2H-[1,4]benzothiazine and 1,2,3,4-tetrahydroquinoline, by 6-aminohexanoyl fragment at the 6-position of purine moiety were obtained. For this purpose, replacement of the chlorine atom in 2-amino-6-chloropurine or 6-chloropurine by direct nucleophilic substitution reaction with 6-aminohexanamides or the coupling of 6-(purin-6-ylamino)-6-hexanoic acid with nitrogen heterocycles were used.

    (ee >97%). This method proved to be less suitable for the preparation of the (S)-enantiomer of 3,4-dihydro-3-phenyl-2H-[1,4]benzothiazine (ee up to 93%) and its sulfone (ee 82%) which were both obtained in low yields. The loss of enantioselectivity for (S)-3,4-dihydro-3-phenyl-2H-[1,4]benzothiazine and its sulfone occurred during hydrolysis of the corresponding diastereoisomerically pure amides.

    Novel purine and 2‐aminopurine conjugates with chiral heterocyclic amines attached at C–6 via ω‐aminoalkanoyl fragment were synthesized. The obtained compounds exhibited inhibitory activity against both herpes simplex virus type 1 (HSV‐1) and acyclovir‐resistant HSV‐1 strains. Anti‐herpesvirus activity of the synthesized compounds depends on their stereo configuration.
