4,4,9,9-Tetraphenyl pyrroloindolizine: a structural analogue of calix[2]pyrrole†
Abstract
Synthesis, spectral and structural characterization of a pyrroloindolizine derivative having structural similarity with calix[2]pyrrole is described. Here, two pyrrole rings are connected with two meso-carbon atoms having an N,α-linkage and an α,β-linkage to afford the smallest analogue in the
