Induction of Molecular Chirality by Circularly Polarized Light in Cyclic Azobenzene with a Photoswitchable Benzene Rotor
Authors: Hashim P. K. , Thomas Reji , Tamaoki Nobuyuki 
Published: May 2011

AbstractNew phototriggered molecular machines based on cyclic azobenzene were synthesized in which a 2,5‐dimethoxy, 2,5‐dimethyl, 2,5‐difluorine or unsubstituted‐1,4‐dioxybenzene rotating unit and a photoisomerizable 3,3′‐dioxyazobenzene moiety are bridged together by fixed bismethylene spacers. Depending upon substitution on the benzene moiety and on the E/Z conformation of the azobenzene unit, these molecules suffer various degrees of restriction on the free rotation of the benzene rotor. The rotation of the substituted benzene rotor within the cyclic azobenzene cavity imparts planar chirality to the molecules. Cyclic azobenzene 1, with methoxy groups at both the 2‐ and 5‐positions of the benzene rotor, was so conformationally restricted that free rotation of the rotor was prevented in both the E and Z isomers and the respective planar chiral enantiomers were resolved. In contrast, compound 2, with 2,5‐dimethylbenzene as the rotor, demonstrated the property of a light‐controlled molecular brake, whereby rotation of the 2,5‐dimethylbenzene moiety is completely stopped in the E isomer (brake ON, rotation OFF), while the rotation is allowed in the Z isomer (brake OFF, rotation ON). The cyclic azobenzene 3, with fluorine substitution on the benzene rotor, was in the brake OFF state regardless of E/Z photoisomerization of the azobenzene moiety. More interestingly, for the first time, we demonstrated the induction of molecular chirality in a simple monocyclic azobenzene by circular‐polarized light. The key characteristics of cyclic azobenzene 2, that is, stability of the chiral structure in the E isomer, fast racemization in the Z isomer, and the circular dichroism of enantiomers of both E and Z isomers, resulted in a simple reversible enantio‐differentiating photoisomerization directly between the E enantiomers. Upon exposure to r‐ or l‐circularly polarized light at 488 nm, partial enrichment of the (S)‐ or (R)‐enantiomers of 2 was observed.
Expanding the Scope of Aminosugars: Synthesis of 2‐Amino Septanosyl Glycoconjugates Using Septanosyl Fluoride Donors
Authors: Saha Jaideep , Peczuh Mark W. 
Published: May 2011

AbstractA general strategy amenable to the strerocontrolled synthesis of complex, ring‐expanded analogues of natural aminoglycosides has been developed. Central to the method is the utilization of septanosyl fluorides as glycosyl donors in facile and selective glycosylation reactions. The septanosyl fluorides proved to be the best choice for the glycosylations because of their accessibility and the scope of aglycones that they could glycosylate. Moreover, a high degree of stereoselectivity was observed in the glycosylations, exclusively giving 1,2‐trans‐glycosides. 2‐Amino septanosyl fluorides were prepared from D‐glucose, D‐galactose, and D‐mannose. Other routes to the septanosyl glyconjugates, especially with regard to alternate donor types, were systematically investigated. Since routes to the individual donor types were being explored, factors that exert a controlling influence on the acid‐mediated cyclization of 1,6‐hydroxy‐aldehydes were determined. The newly prepared 2‐amino septanosyl glycoconjugates illustrate the scope of the reaction and how it may be utilized for the preparation of other ring‐expanded analogues of glycosylated natural products.
