Chemically, fluoroquinlones are an amphoterics molecule processing major ionizable groups, a basic piperazine amine and acidic carboxyl. The form of drugs was greatly affected by the acidity in aqueous solution. Thus the effect of pH values in aqueous solution on the fluorescent properties of fluoroquinolones was studied in details, the spectral properties of each form was characterized. It was found that the fluoroquinolones exhibit weak fluorescence in strong basic solution.

The dissertation mainly consists of two parts:1. The Reaction Chemistry of Alkynes under Palladium Catalysis Part 1 studies the reaction α,β-unsaturated carbonyl compounds with alkenylpalladium intermediate generated by nucleopalladation, and discovered 1 the Pd-catalyzed tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls,2 the four-component tandem addition reaction of halides, alkynes and α,β-unsaturated carbonyls, 3 the tandem intramolecular oxypalladation-conjugate additionreaction of alkynoic acids with α,β-enals. These new reactions provide notonly efficient highly stereoselective methods for the synthesis of γ,δ-unsaturated,polyunsaturated carbonyl compounds and γ-lactonic aldehydes, but also thebasic transformations for a number of C-C bond formation reactions which can be usedto design synthesis of many acyclic, cyclic or polycyclic compounds.
