| Outline of Final Research Achievements |
The microwave specific effect was verified in the Nazarov cyclization reaction. Based on the quantification of the reaction acceleration by kinetic analysis, the maximum acceleration of 5.8 times was confirmed. Reaction acceleration was also observed in the thermal Nazarov cyclization reaction without any loss of chiral transfer rate. In the development research of absolute asymmetric synthesis using circularly polarized microwaves, a joint research was made on the setting of reaction system by physical measurement of circularly polarized microwaves. Furthermore, we have developed a joint research on the hypothesis that the microwave specificity effect is based on entropy effect, and found a possibility to elucidate the mechanism by terahertz spectroscopy.
