A practical synthesis of 11-membered C 2-symmetric binaphthyl ketone (R)-1, a catalyst for asymmetric epoxidation, was developed. (±)-1,1'-Binaphthyl-2,2'-dicarboxylic acid [(±)-6] was efficiently resolved by (R)-(-)-1-cyclohexylethylamine to give (R)-6 in...

A chemo- and regioselective copper-catalyzed cross-coupling reaction for effective amination of 2-chlorobenzoic acids with aniline derivatives has been developed. The method eliminates the need for acid protection and produces a wide range of N-aryl...

Abstract
An efficient synthetic method for the construction of trans-tetrahydrofuran (THF) unit from trans-1,5,9-decatriene was successfully developed by means of Sharpless AD reactions and oxidative cyclizations catalyzed by Co(modp)2 under an oxygen...
