These common heterocyclic compound, 79722-21-7, name is tert-Butyl benzyloxycarbamate, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Computed Properties of C12H17NO3
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 tert-Butyl benzyloxycarbamate has been constantly updated, and we look forward to future research findings.
