Organocatalytic 1,3-dipolar cycloaddition reaction of α,β-unsaturated ketones with azides through iminium catalysis†
Abstract
1,3-Dipolar cycloaddition reaction of α,β-unsaturated ketones with azides through iminium catalysis has been developed. This method could furnish 1,4,5-trisubstituted 1,2,3-triazoles in good yields and high levels of regioselectivity.
