Abstract

Under mild conditions, C3-quaternary 2H-pyrrolines can be convergently and efficiently assembled by Cu(II) and weak bases cocatalyzed [3+2] cycloaddition of 1,1-disubstituted alkenes and isocyanoacetates. Various functionalities can be tolerated, affording 2H-pyrrolines with up to two quaternary centers in a single step.

Keywords: 2H-pyrroline, copper catalysis, isocyanoacetate, isonitrile, cycloaddition, quaternary carbon.

The relative stereochemistry was assigned by a similar method reported in Crich, D.; Banerjee, A. Acc. Chem. Res., 2007. 40, 151- 161. As a result of the shielding effect of the phenyl, the C-2 ester group appeared in a more upfield domain in the endo configuration when compared to the exo configuration.

In this reaction, Cu(I) and Cu(II) showed similar catalytic activity minght be due to that Cu(II) would disproportionate into Cu(I) in the reaction. Cu(I) might be the catalyticall active species in the reaction. 2002.
