Title:
PRODUCTION METHOD FOR 1,1'-BINAPHTHYL DERIVATIVE, AND 1,1'-BINAPHTHYL DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2017/145716
Kind Code:
A1
Abstract:
In this production method according to the present disclosure, a 1,1'-binaphthyl derivative precursor having, at each of the 2-position and 2'-position of a 1,1'-binaphthyl skeleton, an electron-donating group including an oxygen atom directly bonded to the skeleton; an organic acid; and an iodinating agent or a brominating agent are mixed together. The production method according to the present disclosure allows obtaining of a 1,1'-binaphthyl derivative in which a substituent is introduced into the 8-position and/or 8'-position of the 1,1'-binaphthyl skeleton. The 1,1'-binaphthyl derivative obtained by the production method according to the present disclosure can be a compound in which a substituent is further introduced into at least one position selected from among the 4-position, 4'-position, 5-position, 5'-position, 6-position, and 6'-position of the 1,1'-binaphthyl skeleton.
