Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 107017-73-2, name is tert-Butyl (1-(hydroxymethyl)cyclopropyl)carbamate, A new synthetic method of this compound is introduced below., 107017-73-2
To a solution of tert-butyl (1-(hydroxymethyl)cyclopropyl)carbamate (3.5 g; 18.7 mmol) and imidazole (2.54 g; 37.4 mmol) in DCM (40 mL) was added TBDPSC1 (4.11 mL;18.7 mmol). The reaction mixture was stirred for 4 h. Water (50 mL) and DCM (20 mL) were added. The two layers were separated and the aq. phase was extracted twice with DCM (2 x 25 mL). The evaporation residue was purified by CC (EA-Hept) to afford the title compound (8.85 g; >95% yield) as a colorless oil.?H NMR (d6-DMSO) oe: 7.64-7.60 (m, 4H); 7.49-7.40 (m, 6H); 7.20 (s, 1H); 3.66 (s, 2H);1.36 (br s, 9H); 1.00 (s, 9H); 0.7 1-0.65 (m, 2H); 0.64-0.60 (m, 2H).MS (ESI, mlz): 426.1 [M+Hj for C25H35NO3Si; tR = 1.11 mm.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
