Efficient optical resolution of water-soluble self-assembled tetrahedral M4L6 cages with 1,1′-bi-2-naphthol†
Abstract
In this paper, a water-soluble racemic self-assembled tetrahedral cage [Fe4L6]4− was successfully resolved into their ΔΔΔΔ and ΛΛΛΛ enantiomers by (R)-/(S)-1,1′-bi-2-naphthol. The enantiomeric excess of the resolved Fe(II) cage was 99%.
