Описание: This thesis focuses on NHC-catalyzed annulation of nitroalkenes, enals and ?,?-unsaturated carboxylic acids. (1) NHCs were found to be efficient catalysts for the [4+2] annulation of ?-substituted nitroalkenes. The scope of Rauhut–Currier reaction was successfully extended to the most challenging ?-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 ?,?-unsaturated carboxylic acids were first successfully employed to generate the ?,?-unsaturated acyl azolium intermediates by using NHC for the enantioselective [3+2] and [3+3] annulations.

Описание: I well remember my introduction to organic chemistry as an undergraduate working in the laboratories of Shelton Bank at SUNY Albany in the early 1970s, and the excitement and frustration attending the piecing together of the details of a reaction mechanism by working backwards from the stable products of the reaction.
