Abstract

Results reveal that the silylcopper catalyst, dimethylphenylsilylcopper(I), efficiently brings about reductive bromination of Hajos dione. Data indicate that the overall production of the CD synthon from Hajos dione jumps from 22% to 47%.

Abstract

Results demonstrate that the silylcopper catalyst, dimethylphenylsilylcopper(I), efficiently participates in the reductive bromination of Hajos dione. Data suggest that the method is reproducible, amenable to scale-up, and high yielding. The yield of the CD synthon from Hajos dione is about 47%.
