Anthraquinone-substituted β-cyclodextins (β-CD) 1-3 have been synthesized by reaction of the corresponding sulfonyl chlorides with β-CD. The anthraquinone-capped β-CD 3 is produced as a mixture of A,C and A,D isomers. Irradiation of 1-3 results in the formation of the corresponding hydroquinones and oxidation of the CD moiety. The main photoproduct from 2 after regeneration of the anthraquinone contains a C6 aldehyde in a hemiacetal or hydrate form. Molecular mechanics suggests that the position of the aldehyde is on the E-glucose ring and that the intramolar H-abstraction reaction shows some selectivity.
