Abstract

Nitrogen‐15 labeled butyl 4,5,6,7‐tetrahydro‐2__H__‐isoindoIe‐1‐carboxylate was prepared via butyl iso‐cyanoacetate from ^15^N‐glycine in an overall 46% yield. This bicyclic intermediate was converted into nitrogen‐15 and carbon‐13 labeled 2,3:7,8:12,13:17,18‐tetrabutanoporphyrin, a useful model system for the sedimentary tetrahydrobenzoporphyrins.

Recent crystallographic evidence of nonplanarity of several prosthetic groups in heme proteins has prompted the design of conformationally distorted synthetic porphyrins in order to assess the consequences of the nonplanarity observed in vivo. The crystal structure of the sterically crowded Fe(III)
