Summary
This thesis focuses on NHC-catalyzed annulation of nitroalkenes, enals and Ü,Ý-unsaturated carboxylic acids. (1) NHCs were found to be efficient catalysts for the [4+2] annulation of Ý-substituted nitroalkenes. The scope of Rauhut{u2013}Currier reaction was successfully extended to the most challenging Ý-substituted alkenes by this method; (2) Enals were successfully used for [4+2] annulations with azodicarboxylates catalyzed by NHC via Þ-addition. Highly enantiopure tetrahydropyridazinones and Þ-amino acid derivatives could be easily prepared by subsequent transformations of the resulting dihydropyridazinones. (4) The readily available Ü,Ý-unsaturated carboxylic acids were first successfully employed to generate the Ü,Ý-unsaturated acyl azolium intermediates by using NHC for the enantioselective [3+2] and [3+3] annulations
