Заглавие : Acylative kinetic resolution of racemic heterocyclic amines with (R)-2-phenoxypropionyl chloride Место публикации : Tetrahedron: Asymmetry . - 2016. - Vol. 27, № 24. - С. 1231-1237 Примечания : Bibliogr. : p. 1236-1237 (15 ref.)

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. Доп.точки доступа: Vakarov, S. A.; Gruzdev, D.A.; Chulakov, E.N.; Sadretdinova, L. Sh.; Tumashov, A. A.; Pervova, M.
