| Outline of Final Research Achievements |
The purpose of this project has been focused on the development of a new selective method for deuteration of organocatalysts and biologically interesting molecules. As a result, we could succeed in synthesizing new deuterated thiourea organocatalysts for the use in novel synthetic reactions. For example, we found that a catalytic system composed of trityl halide and thiourea catalyst could serve as novel organo-based Lewis acids for the use in carbonyl-ene cyclization. In addition, we also found that the asymmetric Michael addition reaction of alpha-substituted cyclic ketones was efficiently promoted by primary amine-based organocatalysts under high pressure conditions. Finally, we could also succeed in obtaining a new approach to introduce deuterium atoms into the biologically interesting molecules. We believe that these results will give important information for other chemists who work in this important field.
