Method for producing 1,1'-binaphthyl derivative and 1,1'-binaphthyl derivative

摘要

In the production method of the present disclosure, a 1,1′-binaphthyl precursor derivative having an electron-donating group containing an oxygen atom directly bonded to the skeleton at the 2-position and the 2′-position of the 1,1′-binaphthyl skeleton, An organic acid is mixed with an iodinating agent or brominating agent. According to the production method of the present disclosure, a 1,1′-binaphthyl derivative having a substituent introduced at the 8-position and / or the 8′-position of the 1,1′-binaphthyl skeleton can be obtained. The 1,1′-binaphthyl derivative obtained by the production method of the present disclosure is at least one selected from the 4-position, 4′-position, 5-position, 5′-position, 6-position and 6′-position of the 1,1′-binaphthyl skeleton. It may be a compound in which a substituent is further introduced at one position.
