Generation and Reactivity of Aza-Oxyallyl Cationic Intermediates: Aza-[4 + 3] Cycloaddition Reactions for Heterocycle Synthesis
摘要:
Aza-[4 + 3] cycloadditions of putative azaoxyallyl cationic intermediates and cyclic dienes are reported. The intermediate is generated by the dehydrohalogenation of alpha-haloamides. The reaction is general to a variety of alpha-haloamides and is diastereoselective. Computational and experimental data suggest that an N-alkoxy substituent stabilizes the aza-oxyallyl cationic intermediate.

The present invention relates to 7-membered nitrogen-containing heterocyclic compounds and methods of making the same. Using a novel aza-[4+3] cycloaddition reaction, the 7-membered heterocyclic compounds are synthesized by reacting a first reactant and a second reactant. Exemplary first reactants and second reactants include α-halohydroxamates and dienes, respectively.
