技术应用

A convenient method for determining the absolute configuration of secondary alcohols.

详细技术说明

Determining the absolute configuration of organic compounds is a challenging problem, but necessary to predict how a compound will react with other chemicals. Several methods for this determination such as x-ray analysis, CD methods, Mosher’s, and VCD with computational analysis are time consuming and labor intensive. The Competing Enantioselective Conversion (CEC) method for determining the absolute stable configuration of alcohols was developed at UCI in 2011. The analysis using CEC is much faster than other state-of-the-art methods, taking only 1-2 hours. Unfortunately, CEC requires a number of solutions with very precise concentrations whose preparation takes much longer than the actual analysis. Furthermore, some of the required chemicals are unstable, preventing the preparation of large batches for future use. For researchers, this means large amounts of samples are collected and the analysis is performed only periodically. Such a drawback is not conducive to time-sensitive development and research. The inventors at UCI have discovered and optimized stable solutions of the reagents necessary for CEC, and prepared a single-use kit for carrying out the analysis. The reagents are prepared in a larger batch that is separated into single-use kits and stored for future use. The kits, which are sealed in an inert gas environment, remain stable for months. Researchers no longer need to wait for a number of samples and can perform the CEC analysis on-demand. Overall, the invention reduces the time and labor for the CEC method and increases its commercial viability. This is particularly important in the Chemical and Pharmaceutical industry.

*Abstract

The absolute configuration of an organic compound dictates its interactions with other chemicals. The Competing Enantioselective Conversion (CEC) method is an attractive method for determining the absolute configuration of secondary alcohols, but the preparation of stock reagent solutions takes longer than the analysis time itself – a mere 1-2 hours. The inventors at UCI have developed a CEC kit which contains stock solutions of the components required for CEC that remain stable and usable for several months.
