-

Yield:91851-17-1 92%

Reaction Conditions:

with bismuth sulfide microspheres in neat (no solvent) at 60; for 2.5 h;chemoselective reaction;

Steps:

Ring opening of epoxides

General procedure: In a typical epoxide ring-opening reaction, the catalyst, Bi2S3 microspheres(30 mg), was added into a solution of 2-phenyloxirane (1mmol) and corresponding nucleophie. The solution was stirred at 60 °Cunder solvent-free conditions and the progress of the reaction wasmonitored using TLC. After completion of reaction, ethyl acetate (20mL) was added and filtrated. Finally, the crude product was subjected tocolumn chromatography on silica gel to obtain the pure product.
