Abstract
THE recent publication of a paper by Woodward and Witkop1 suggesting a new structure for ketoyobyrine, based on degradative evidence, and of another by Schlittler and Speitel2, claiming the synthesis of this substance, prompts us to point out that on May 28, 1948, we submitted to the Chemical Society a paper describing the synthesis of ketoyobyrine. This has been accepted for publication in the Journal; but unfortunately its appearance cannot be expected for many months.
