Studies On The Photochemistry Of Quinolone Dervative On The Gel State

Researches on photochemistry and chiral substances have attracted much attention inrecent years, espesially the research of enantiomers and diastereomer excess of prochiralsubstances in a chiral environment has become a hot focus. However, most experiments weredone in homogeneous solution and solid phase conditions; Photoreactions in gel state wererare.In this paper, a series of double substituted amide compounds with chiral groups as lowmolecular organogelators (LMOGs) were designed and synthesized based on3,4,5-tris(hexadecyloxy)benzoic acid. Small molecule gelator of mannide was synthesizedfrom D-mannitol.The synthesized compounds were characterized by1H NMR,13C NMR,FTIR spectrum and MS. The gelation ability was tested in various solvents and themicrostructure was characterized. Besides, research on the stereoselectivity of the prochiralsubstrate (quinolinone derivative) phtocyclization was studied with the addition of chiralinductive gelator, especially the reaction take place at gel state. Structural isomers reduced bytwo gel formation of ketones gelator and light reaction substrate, compared to the gel statephotoreaction in the presence of a catalyst in liquid, the light reaction products wassignificantly different.
