HCID 123488148(S)-(5-Fluoro-2-(pent-4-en-2-yloxy)phenyl)boronic acid収率 100%

実験手順

Prepared from (S)-2-bromo-4-fluoro-1-(pent-4-en-2-yloxy)benzene in 100% yield following the same procedure as (S)-(4-fluoro-2-(pent-4-en-2-yloxy)phenyl)boronic acid. NMR is complex and suggests an oligomeric mixture. The material, however, was used as is and was fully compentent for undergoing a Suzuki coupling.
