Electro- and Photoactive Molecular Assemblies of Liquid Crystals and Physical Gels |
|
Takashi Kato and Kana Tanabe |
| [Full Text PDF(J-STAGE)] Open Access Article |
 |
|
Self-organized structures of liquid crystals and self-assembled fibers have great potential as new functional materials. This article highlights self-organization of π-conjugated molecules, leading to the induction of photonic, electronic, and electrochemical properties. |

Nonenzymatic Regioselective Acylation of Carbohydrates |
|
Takeo Kawabata and Takumi Furuta |
| [Full Text PDF(J-STAGE)] |
 |
|
A nonenzymatic one-step procedure for the chemo- and regioselective acylation of carbohydrates has been developed. With 1 mol % of an organocatalyst, acylation of octyl β-D-glucopyranoside took place preferentially on the secondary hydroxy group at C(4) among four hydroxy groups including the primary hydroxy group at C(6) in 99% selectivity and in 98% yield. This could be alternatively achieved by a conventional protection/deprotection procedure via five steps and in 46% overall yield. Thus, development of the present process is expected to contribute to extremely shorten synthetic routes for carbohydrates. |
