An Enantioselective Fluorescent Sensor for Sugar Acids
摘要:
Chiral fluorescent boronic acid 1 was found to be a highly enantioselective, chemoselective, and sensitive sensor for sugar acids, such as tartaric acid. Enantioselectivities (K-R/K-S) of up to 550:1, chemoselectivity up to 11000:1, and sensitivities in the micromolar range with sensor 1 were observed. Single-crystal X-ray analysis was used to confirm the structure of the fluorescent species.

Disclosed is a method for producing an optically active 3-methylcyclopentadecan-1-one which is characterized in that 2-cyclopentadecen-1-one is subjected to a 1,4-conjugate addition reaction of a methyl group by using a methylated organic metal in the presence of a copper catalyst, an enol anion scavenger and a specific optically active phosphoramidite for obtaining an optically active 3-methyl-1-cyclopentadecene derivative, and then the thus-obtained 3-methyl-1-cyclopentadecene derivative is subjected to a solvolysis.
