Adding a certain compound to certain chemical reactions, such as: 2919-23-5, Cyclobutanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 2919-23-5, blongs to alcohols-buliding-blocks compound. Formula: C4H8O
To a solution of N-Boc-L-alanine (4: 15.5 g, 81.9 mmol) in dichloromethane (300 ml), DCC (16.9 g, 81.9 mmol)was added at 0C and 5 min later, cyclobutanol (3: 5.6 g, 78.0 mmol) and DMAP (2.0 g, 16.4 mmol). The mixture wasstirred overnight evaporated in vacuum , and the residue was treated with ethyl acetate (300 ml). The residue was filteredoff and washed with ethyl acetate. The filtrate was washed with a 5% solution of citric acid (2 x 100 ml), a saturatedNaHCO3 solution (2 x 100 ml), and brine, dried over Na2SO4, and evaporated in vacuum to afford 19.6 g (98 %) of(S)-cyclobutyl 2-(tert-butoxycarbonylamino)-propanoate (5) as a white powder. 1H NMR (400 MHz, DMSO-d6) delta 7.22(d, J = 7.2 Hz, 0.85H), 6.87 (m, 0.15H), 4.89 (p, J = 7.2 Hz, 1H), 3.94 (m, 1H), 2.26 (m, 2H), 1.98 (m, 2H), 1.74 (m, 1H),1.59 (m, 1H), 1.38 (s, 7.5H), 1.34 (brs, 1.5H), 1.22 (d, J = 7.2Hz, 3H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,2919-23-5, its application will become more common.
