Paragraph 0320-0322; 0334-0336, (2020/06/18)
PROBLEM TO BE SOLVED: To provide: a production method of a benzothiazole derivative; as well as a production method of a polymerizable compound produced from the benzothiazole derivative; a polymerizable composition including the polymerizable compound; a polymer obtained by polymerizing the polymerizable composition; and an optical isomer utilizing the polymer. SOLUTION: A production method of a compound represented by the following general formula (III) is provided, and also a production method of a polymerizable compound produced from the compound represented by the general formula (III), a polymerizable composition, a polymer obtained by polymerizing the polymerizable composition, and an optical isomer utilizing the polymer are provided. When the polymerizable composition containing the compound is polymerized and the obtained film-like polymer is irradiated with ultraviolet light, change of color and change of phase difference scarcely take place.

The preparation of new chiral symmetrically and unsymmetrically N,N′-disubstituted imidazolium based NHC salts Ib, IIb, IIIa-c and IVc-h from the amino acids l-proline and l-phenylalanine, is reported. Some preliminary tests have been carried out, demonstrating that the chiral NHCs give chiral induction in organometallic catalysis and can be used as organocatalysts.
