Gang He, Jing Wang, and Dawei Ma Highly Convergent Route to Cyclopeptide Alkaloids. Total Synthesis of Ziziphine. 10.1021/ol062639z. The original paper was published ASAP on 11/23/06 but will not appear in a print issue for the following reason. Recently, we got the 1H NMR spectrum of natural ziziphine N and found that our spectrum does not exactly match with it. We now wonder if our previous conclusions which resulted from simply comparing reported data is correct. To avoid any mistakes, we are reevaluating our conclusions.
