Preparation of enantioenriched helical- and axial-chiral molecules by dynamic asymmetric induction

Abstract

DYASIN of racemic dynamic chiral heterohelicenes afforded their highly enantioenriched forms in quantitative yields. These heterohelicenes were readily converted into semi-static axial-chiral 1,1′-binaphthyl derivatives in a stereospecific manner.

Stereochemical study on planar‐chiral cyclic molecules using polysaccharide‐based column chromatography

“…Further studies on planarchiral cyclic molecules, including dynamic asymmetric induction (DYASIN) using polysaccharide-based chiral stationary phase, are underway. 44,45…”

“…In summary, we described a story of our planar‐chiral cyclic molecules from the beginning until recent, with a central focus on the importance of polysaccharide‐based column chromatography. Further studies on planar‐chiral cyclic molecules, including dynamic asymmetric induction (DYASIN) using polysaccharide‐based chiral stationary phase, are underway 44 , 45 …”
