3-Mercaptopropionic acid, 3-MPA

Recent Literature

Various alkyl and aryl sulfoxides have been successfully deoxygenated using 3-mercaptopropionic acid as a reducing agent and a catalytic amount of either NBS or I2 in MeCN at ambient temperature. Under the described reaction conditions, acid sensitive substrates such as acetals remained intact.
