The 4-(4-(5-phenyl-4,5-dihydroisoxazol-3-yl)thiazol-2-yl)aniline (0.321 g 1 mmol) and Boc–l-alanine (0.100 g 1.05 mmol) in pyridine (5 mL) were stirred in a 25 mL flask. The reaction progress was monitored by TLC. The mixture was poured into iced water, and the solution was filtered to obtain intermediate. After, the intermediate was dissolved in dichloromethane (10 mL), then trifluoroacetic acid (2 mL) was slowly added at room temperature. The mixture was evaporated and then saturated aqueous NaHCO3 was added. The crude product was purified by column chromatography (EA: MeOH = 10:1, v/v) to give 2-amino-N-(4-(4-(5-phenyl-4,5-dihydroisoxazol-3-yl)thiazol-2-yl)phenyl)propanamide. Next, 2-amino-N-(4-(4-(5-phenyl-4,5-dihydroisoxazol-3-yl)thiazol-2-yl)phenyl)propanamide was dissolved in acetone (10 mL) and heated at 60 °C for 30 min. At last, the reaction mixture was allowed to recrystallize from acetone to obtain 2,2,5-trimethyl-3-(4-(4-(5-phenyl-4,5-dihydroisoxazol-3-yl)thiazol-2-yl)phenyl)imidazolidin-4-one. 1H NMR (400 MHz, CDCl3) d 8.04–8.00 (m, 2H), 7.80 (s, 1H), 7.45–7.37 (m, 4H), 7.35–7.31 (m, 1H), 7.30–7.26 (m, 2H), 5.78 (dd, J = 11.1, 8.3 Hz, 1H), 5.30 (s, 1H), 3.95 (dd, J = 17.3, 11.1 Hz, 1H), 3.76 (q, J = 6.9 Hz, 1H), 3.54 (dd, J = 17.3, 8.3 Hz, 1H), 1.49–1.46 (m, 6H), 1.45 (s, 3H).

All hydrogen atoms were placed in the calculated positions and constrained to ride on their parent atoms. Using Olex, 2 the structure was solved with the XM 3 structure solution program using Dual Space and refined with the XL. 3

3 Comment

Nitrogen-containing heterocycles are widely found in natural products and pharmaceuticals. 4 , 5 Isoxazoline is an important scaffold of pesticide active molecules. Most of its derivatives have high-efficiency and broad-spectrum agricultural activities such as insecticidal, 6 , 7 bactericidal 8 , 9 and herbicide. 10 , 11 The thiazole rings exhibit a wide range of biological activities and have found extensive applications in the development of environmentally friendly pesticides. 12 , 13 The investigation of single crystal structures of isoxazoline-thiazoles is crucial in elucidating their structure-activity relationships, given their wide range of physiological activities and significance in drug development.

The title compound crystallizes in the orthorhombic P212121 space group. In the crystal structure (figure), the presence of chirality of C7 in the title molecule exhibits an R configuration. The bond length of C11=S1 and C12=S1 are 1.715 and 1.746 Å, respectively. The dihedral angle between the isoxazoline ring and the thiazole ring is 10.01(18)°. The torsion angles of C1–C7–O1–N1, C9–N1–O1–C7, C16–N3–C19–C20 and C16–N3–C21–N4 are −155.3(4)°, 17.2(5)°, 164.6(4)° and −177.2(4)°, respectively. All bond lengths and angles are within a reasonable range. 14 , 15
