General procedure: The reaction formula of this embodiment is as follows: 1) Under air, IMesCuCl (3 molpercent),Potassium carbonate (1.1 eq), bis(pinacolato)diboron (1 eq) was added to a pressure-resistant sealed reaction tube containing a magnetic particle. After filling with acetylene,3 mL of tetrahydrofuran was added to the reaction tube.Stir at room temperature for 20 minutes,Then add triisopropylsilyl bromoacetylene (0.25 mmol) to the reaction solution,The reaction was stirred in a 30 ° C oil bath for 12 hours.(2) The material obtained in the step (1) is cooled to room temperature, and thoroughly mixed with ethyl acetate. After filtering off the solid residue with a short silica gel column, the organic phase was retained.(3) spinning the solvent in the organic phase obtained in the step (2) to obtain a crude product.The crude product was then purified on a silica gel column. The eluent is a mixed solution of petroleum ether and ethyl acetate.And the ratio of petroleum ether to ethyl acetate is 50:1. The isolated yield was 78percent.The product was 99percent pure. The prepared product was subjected to structural characterization, and the results are shown in Table 1. |
