Abstract

We report the syntheses of renieramycin M along with so-called fennebricin A from jorunnamycin A, which was prepared from pentacyclic lactam intermediate 4 in our previous total synthesis of renieramycin G, as well as the re-assignment of the NMR data of fennebricin A, which offered very important information for structure elucidation.
