Significance

Baran and Richter convert (S)-carvone oxide to Welwitindolinone A and Fischer­indoles I and G in seven and eight steps, respectively, without the use of a single protecting group. It is noteworthy that all the necessary carbon atoms of the target molecules were secured in only three steps.
