14447-18-8, name is Benzyl cyanoacetate, belongs to nitriles-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Computed Properties of C10H9NO2
A. 2-Cyano-4-ethyl-hex-2-enoic acid benzyl ester To a mixture of 2-ethylbutyraldehyde (2.0 mL, 16.2 mmol) and benzyl cyanoacetate (2.85 g, 16.2 mmol) at 0 C. was added acetic acid (0.1 mL, 1.62 mmol), then piperidine (0.16 mL, 1.62 mmol) dropwise. The ice bath was removed, and stirring continued for 10 minutes. Additional acetic acid (0.1 mL) and piperidine (0.16 mL) were added, followed by the additional of oven-dried 4A molecular sieves such that stirring was not impeded. The mixture was stirred 1.5 h, then partitioned between EtOAc and sat. NaHCO3 (aq). The phases were separated, and the organic phase washed with brine, dried (MgSO4), and concentrated to provide 3.96 g (95%) of 2-cyano-4-ethyl-hex-2-enoic acid benzyl ester as a colorless oil. 1H NMR (CDCl3) delta 7.39 (m, 6H), 5.28 (s, 2H), 2.60 (m, 1H), 1.62 (m, 2H), 1.40 (m, 2H), 0.88 (t, J=7.6 Hz, 6H). 13C NMR delta 168.69, 161.40, 135.01, 128.90, 128.82, 128.50, 114.11, 109.94, 68.07, 46.35, 27.30, 11.95. IR (neat) 2233, 1729 cm-1. LRMS: m/z 256.1 (M-1). Anal. Calcd for C16H19NO2: C, 74.68; H, 7.44; N, 5.44. Found: C, 74.75; H, 7.52; N, 5.50.
The synthetic route of 14447-18-8 has been constantly updated, and we look forward to future research findings.
