Herein, we report the selective mono-derivatization of heptakis[6-deoxy-6-(2-aminoethylsulfanyl)]-β-CD (1) through a guest-mediated covalent capture strategy. The use of guests functionalized with cleavable linkers enables the installation of an amine-orthogonal thiol group on the primary rim of 1 as a handle for further transformations to the β-CD scaffold. Applying this methodology, two novel monoderivatized β-CDs were obtained in good yield and high purity. Both of these monoacylated CDs were amenable to facile linker cleavage and further modification at the resulting thiol group. This methodology can be applied towards the synthesis heterofunctionalized β-CD constructs for analyte sensing, drug delivery, and other applications.
