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. 123986-64-1, name is tert-Butyl 4-(hydroxymethyl)benzylcarbamate, A new synthetic method of this compound is introduced below., Recommanded Product: tert-Butyl 4-(hydroxymethyl)benzylcarbamate
Dess-Martin periodinane (1.25 eq) was added to a flask with a stir bar. Diluted with DCM (0.25 M), and the resulting slurry was stirred vigorously at roomtemperature. Added a solution of alcohol (1.00 eq) in DCM (0.20 M) in dropwise fashion, and the resulting reaction mixture was stirred vigorously under Ar at room temperature. After 2.5 hrs, TLC indicated complete conversion of starting material. The reaction mixture was poured over a 1:1 mixture of saturated aqueous NaHCO3 and saturated aqueous Na2S2O3 (55 mL per mmol alcohol). The resulting organic layer was dried over anhydrous sodium sulfate, filtered, and evaporated under reduced pressure. A solution ofamine (1.00 eq) in DCM (0.12 M) was added to a flask with a stir bar. Added a solution of aldehyde (1.05 eq) in DCM (0.53 M), and the resulting mixture was stirred under Ar at room temperature for 5 mm. After this time, acetic acid (1.00 eq) was added, and the resulting mixture was stirred under Ar at room temperature for 15 mm. After this time, sodium triacetoxyborohydride (3.00 eq) was added, and the resulting reaction mixture was allowed to stir overnight at room temperature under Ar. In the morning, thereaction mixture was diluted with DCM and washed once with 1 M aqueous sodium hydroxide. The resulting aqueous layer was extracted 3 times with DCM. Combined organic layers were dried over anhydrous sodium sulfate, filtered, and evaporated under reduced pressure. The cmde material was taken up in DCM (40 mL per mmol amine), filtered, and evaporated under reduced pressure.
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.
