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. 79722-21-7, name is tert-Butyl benzyloxycarbamate, A new synthetic method of this compound is introduced below., name: tert-Butyl benzyloxycarbamate
General procedure: Nucleophile (1-3 mol equiv), tris-(dibenzylideneacetone)dipalladium (2.5 mol %), tris-(2-furyl)phosphine (10 mol %) and potassium carbonate (2 mol equiv) were added to a solution of the aryl halide (1 mmol) in dry dimethylformamide (10 mL) in a Schlenk tube. The reaction mixture was then degassed using the freeze, pump, thaw (F.P.T.) technique (one cycle). Allene gas was then introduced at the required pressure (1 atm) and the Schlenk tube contents stirred and heated at 80 C for 16 h. After cooling and venting, DCM (20 mL) was added and the mixture filtered to remove inorganic salts. The filtrate was concentrated in vacuo and the residue was purified by column chromatography.
The synthetic route of 79722-21-7 has been constantly updated, and we look forward to future research findings.
