(9R,9aS,12aR,13S)-9,13-Diphenyl-9,9a,12a,13-tetrahydro-9,13-methanotriphenyleno[2,3-c]furan-10,12,14-trione
Round 1
Reviewer 1 Report
In this manuscript the Authors carried out the synthesis, crystallization and characterization (1H-NMR, 13C-NMR, IR and X-ray) of the title compound. These data confirm that cycloaddition yields the endo isomer as a unique product and provide a compelling explanation regarding the thermal instability of this adduct.
Supporting information can be improved by adding a caption indicating the solvent used for NMR analysis and definitively removing the integration peaks of the residual non-deuterated solvent from the 1H-NMR spectrum
Some typos can be found in the manuscript (for ex. "that that" line 50 page 2)
Author Response
Thank you very much for these comments, they are very helpful. The SI document will be updated as suggested and the typos corrected.
