Outline of Final Research Achievements |
Vibrational circular dichroism (VCD) is a reliable and non-empirical method which can determine absolute configuration. However, ab initio theoretical calculation for its conformational analysis of a target molecule is essential. In this project, a new methodology for determination of absolute configuration without its theoretical calculation has been developed by utilizing a huge bisignate VCD signal caused by their interaction of two IR functional groups such as carbonyl groups in a target molecule. This novel methodology named as “VCD exciton chirality method” has been applied to a variety of carbohydrates, steroids, complex natural products, acyclic biological active lipids, and poly lactic acid as a polymer, which shows its high applicability.
