WebABSTRACT: Folate-conjugated cryptophane was developed for targeting cryptophane to membrane-bound folate receptors that are overexpressed in many human cancers. The cryptophane biosensor was synthesized in 20 nonlinear steps, which included functionalization with folate recognition moiety, solubilizing peptide, and Cy3 ﬂuorophore. WebAfter deprotection with a palladium catalyst, mono-allylated cryptophane-A (1, 2) and cryptophane-E (3) gave the new cryptophanols 4, 5 and 6, respectively, which are important key compounds for the preparation of mono-functionalized cryptophanes as well as for the design of large supramolecular hosts such as the bis-cryptophanes 7 and 8.
