Mode opératoire
Cyclohex-3-enecarboxylic acid (0.71 mmol, 90 mg), NH2CH2CH2CH3 (0.86 mmol, 70 μL) and EDC.HCl (0.86 mmol, 164 mg) were dissolved in CH2Cl2 (3 mL). DIEA (1.43 mmol, 252 μL) was added at 0° C., and the reaction was stirred for 16 h at rt. The usual workup and chromatography (Acetone/CH2Cl2/10:90) yielded N-propylcyclohex-3-enecarboxamide 26 as a white powder (65 mg, 55%). 1H NMR (400 MHz, CDCl3) δ 5.64 (m, 3H), 3.17 (dd, J=8 Hz, J=8 Hz, 2H), 2.30-1.93 (m, 5H), 1.87-1.81 (m, 1H), 1.72-1.59 (m, 1H), 1.43 (m, 2H), 0.87 (t, J=8 Hz, 3H). 13C NMR (100 MHz, CDCl3) δ 175.93, 126.94, 125.61, 41.52, 41.22, 28.35, 25.97, 24.80, 23.07, 11.49.
