Monitoring solution-phase combinatorial library synthesis by capillary electrophoresis.
Capillary electrophoresis has been applied to monitor model reactions in solution-phase combinatorial chemistry. In particular, the simultaneous alkylation reactions of secondary amines with a series of benzyl halides has been investigated. Reactant and product concentrations were monitored using capillary electrophoresis in a non-aqueous buffer system. The simplified sample preparation was a key feature making this an attractive method of analysis. The results demonstrate that capillary electrophoresis is a useful tool for monitoring reactions to determine initial rates, rate constants, and extinction correlation coefficients for quantitative analysis in combinatorial chemistry, and is a broadly applicable technique for the analysis of a variety of organic and bioorganic transformations.
