The planar structure and the relative configuration of 1 were established on the basis of extensive analysis of its spectroscopic data, while its absolute configuration was determined by comparison of its experimental and quantum-mechanically predicted electronic circular dichroism spectra. © 2019 American Chemical Society." }
