Source of material
The reaction of diglycolic acid (6.7 g, 50 mmol) and benzylamine (5.4 g, 50 mmol) yielded the product (6.1 g, 60%) as colorless crystals. A solution of potassium bis(trimethylsilyl)amide (KHMDS) (1.159 g, 5.81 mmol) in tetrahydrofuran (THF) (20 mL) was cooled to −78 °C under argon. Subsequently, a solution of the colorless crystals that have been obtained (0.500 g, 2.32 mmol) [4], distilleddiphenyl chlorophosphate (1.373 g, 5.11 mmol), and distilled hexamethylphosphoramide (HMPA) (1.041 g, 5.81 mmol) in THF (5 mL) was added dropwise over 5 min. After 15 min at −78 °C, the reaction mixture was diluted with diethyl ether (50 mL). Water (50 mL) was then added, and the mixture was extracted with EtOAc. The organic phase was dried over anhydrous MgSO4 and concentrated. Flash chromatography (petroleum ether/EtOAc, 7:3 + 0.1% NEt3) was used to obtain the title compound as colorless block.
Experimental details
All hydrogen atoms were placed in the calculated positions and all the non-hydrogen atoms were refined anisotropically.
Comment
Heterocyclic compounds constitute one of the largest and most versatile families of organic compounds [5, 6]. There are many heterocyclic compounds that are being isolated from natural sources and day by day the number is increasing rapidly due to their enormous utility [7]. N-heterocycles are important, not only because of their abundance, but above all because of their chemical, biological and technical significance [8, 9].
In the molecules forming the title crystal structure, the dihedral angle of ring formed by C8–C11 and the moiety formed by C7–C11 is 26.4°. The dihedral angle between the phenyl ring formed and the ring formed by C8–C11 is, close to a right angle. The bond lengths and angles are in the expected ranges.
