Selective modification of β-cyclodextrin: an unexpected tandem reaction enables the cross-linking of C2A and C2B via a sulfur atom
Abstract
2A,3A-Alloepithio-2B-sulfonyl-β-cyclodextrin undergoes a tandem reaction to generate an unprecedented C2A–S–C2B-bridged glucosyl-3A,6A-anhydroglucoside segment.
