Polyfunctionalized 2-(furan-2-yl)pyrroles and 2-(furan-3-yl)pyrroles derived from 2-azetidinone-tethered alienes by two independent cerium(IV)-mediated single-electron oxidations provided a (4-oxopent-2-enoyl) pyrrole and 3,3′-bis(pyrrol-2-yl)-2, 2′-bifurans, respectively. Access to the oxidation precursors was achieved by regiocontrolled cyclization of β-allenamine intermediates derived from selective β-lactam nucleus breakage of 2-azetidinone-tethered allenols.

A new one-pot approach to synthesize densely substituted racemic and enantiopure pyrroles from β-lactams has been developed. The approach relies on the regiocontrolled cyclization of β-allenamine intermediates derived from the ring opening of 2-azetidinon
