New Strategies for N-Heterocyclic Carbenes Catalyzed Annulations
This thesis focuses on NHC-catalyzed annulation of nitroalkenes, enals and a,ß-unsaturated carboxylic acids. (1) NHCs were found to be efficient catalysts for the [4+2] annulation of ß-substituted nitroalkenes. The scope of Rauhut-Currier reaction was successfully extended to the most challenging ß-substituted alkenes by this method; (2) Enals were successfully used for [4+2] annulations with azodicarboxylates catalyzed by NHC via ¿-addition. Highly enantiopure tetrahydropyridazinones and ¿-amino acid derivatives could be easily prepared by subsequent transformations of the resulting dihydropyridazinones. (4) The readily available a,ß-unsatur…
