Regioselectivity in the 1,3-dipolar cycloaddition of muenchnones with two electrophilic alkynes. Attempt of rationalization.

The 1,3-dipolar cycloaddition reaction of several unsymmetrically substituted muenchnones with methyl propiolate 3a and with methyl 3-phenylpropiolate 3b has been examined.The reaction generally proceeds with formation of mixtures of both possible regioisomeric pyrroles.The dipolarophile 3b is more selective than 3a in accordance with the literature.Sustmann's variation-perturbation theory could not account for the observed regioselectivities, this theory gives correct predictions with alkenes as we have shown recently. 1,3-cycloaddition / muenchnones / pyrroles / regioselectivity
