Arylazide cycloaddition to methyl propiolate: DFT-based quantitative prediction of regioselectivity

Several 1-(4-substituted)-phenyl-4- or 5-methoxycarbonyl-1,2,3-triazoles have been synthesized by 1,3-dipolar cycloaddition of the corresponding arylazides to methyl propiolate in carbon tetrachloride. The regioselectivity of these reactions cannot be rat

KINETICS AND MECHANISM OF THE 1,3-DIPOLAR CYCLOADDITION OF PHENYL AZIDES TO METHYL 3-PYRROLIDINOACRYLATE

Kinetics of cycloaddition of phenyl azides to methyl 3-pyrrolidinoacrylate (2) produced Hammett ρ=2.2.An Ea of 13.5 kcal mole-1 and ΔS* of -37.4 cal.K.-1 mole-1 were calculated for the cycloaddition of p-O2NC6H4N3 to 2.The cycloadditions are concerted, non-synchronous, and are controlled by LUMO (azide) - HOMO (dipolarophile) interactions.
