Regioselectivity of 1,3-Dipolar Cycloaddition Reactions of C-Acetyl-N-arylnitrilimines with Acrylic Acid Derivatives and α,β-Unsaturated Ketones

Article abstract of DOI:10.1021/je00056a032

The cycloaddition of a series of C-acetyl-N-arylnitrilimines 6a-e to acrylamide (2a), acrylonitrile (2b), and substituted benzylideneacetophenones 4a-d has been studied.Under thermal conditions, these 1,3-dipolar cycloadditions proceed with absolute regio
