Conversion of racemic 2-hydroxymethyl[5]thiaheterohelicene into a single enantiomer on the uptake by bovine serum albumin
Abstract
Racemic 2-hydroxymethylthieno[3,2-e:4,5-e′]di[1]benzothiophene with a labile helical structure was converted into a (P) enantiomer upon uptake by bovine serum albumin, in which the existence of two substrate-binding sites with a distinct ability to recognize chirality was revealed.
