  Development of Cyclic Hydrazine and Hydrazide Type Organocatalyst ⎯ Mechanistic Aspects of Cyclic Hydrazine/Hydrazide-Catalyzed Diels-Αlder Reactions

  摘要：

  Some hydrazines and hydrazides were prepared and screened for their catalytic efficiencies in Diets-Alder reactions. H-1-NMR studies and ab initio calculations revealed that catalytic efficiencies of these catalysts are greatly dependent on the release of the catalysts from the Diels-Alder adducts.

  A new scaffold for organocatalysis of the Diels-Alder reaction is disclosed; an isoxazolidine ring forms the core of the catalyst and its activity is enhanced by judicious fusion of a second five-membered heterocycle to the c-edge. The catalyst performance is improved by the incorporation of an endo-cyclic electron withdrawing group adjacent to the fusion point. The organic core is effective only in the presence of an acid co-catalyst and whilst the two-component system shows potential as an enantioselective catalyst it is demonstrated that stereocontrol is a feature of the organic core and is fully independent of the choice of co-catalyst.
