Abstract: Abstract A series of 6 A ,6 X -diguanidio- γ -cyclodextrins (CDs) were used as chiral hosts for mediating the enantiodifferentiating [4 + 4] photocyclodimerization of 2-anthracenecarboxylic acid (AC). These γ -CD derivatives form stable 1:2 ternary… read more here.

Abstract: Stereoisomeric β-cyclodextrin (CD) dimers linked with a sulfur atom or an arene spacer were designed to create a tethered dual CD capsule for precisely manipulating the regio- and enantioselectivities of the photocyclodimerization of 2-anthracenecarboxylate (AC)… read more here.
