A novel method for the preparation of corroles with beta-fused pyrazino rings was developed, exploiting a one-pot reaction of 2,3-diaminocorroles (or 2,3,17,18-tetraaminocorroles) with different diones; a variety of pi-extended corroles were obtained in moderate yields as copper complexes, which can then be de-metallated to give the corresponding free base in good yields.

Abstract
A novel method for the preparation of corroles with beta-fused pyrazino rings was developed, exploiting a one-pot reaction of 2,3-diaminocorroles (or 2,3,17,18-tetraaminocorroles) with different diones; a variety of pi-extended corroles were obtained in moderate yields as copper complexes, which can then be de-metallated to give the corresponding free base in good yields.File | Dimensione | Formato | |
