Syntheses of bridged fenestranes via stepwise intramolecular Diels–Alder reaction and nitrone cycloaddition and their structural analyses

Fenestranes contain four rings sharing one carbon atom and have garnered considerable attention because of their physicochemical properties. We synthesized bridged fenestranes with an asymmetrical skeleton via stepwise cycloadditions including intramolecular Diels–Alder reaction and nitrone cycloaddition. A total of nine fenestranes were synthesized, and the obtained framework was modified to access different derivatives. X-ray crystallography analysis and DFT calculations of the fenestranes revealed that the central carbon was sufficiently flattened even when the fenestrane skeleton was partially cleaved., NMR spectroscopy, DFT calculations, , , # Data from: Syntheses of Bridged Fenestranes via Stepwise Intramolecular Diels–Alder Reaction and Nitrone Cycloaddition and their Structural Analyses # Description of the data and file structure This dataset contains experimental and computational data supporting the associated ACS manuscript. ### NMR_raw_1.zip Raw NMR data files in .jdx JCAMP-DX data for accessibility format and original JEOL .jdf data reported in the manuscript.\ Includes ^1^H and ^13^C NMR spectra.\ Files are named according to the compound numbers in the manuscript. ### NMR_raw_2.zip Raw NMR data files in .jdx JCAMP-DX data for accessibility format and original JEOL .jdf data reported in the manuscript.\ Includes ^1^H and ^13^C NMR spectra.\ Files are named according to the compound numbers in the manuscript. ### NMR_raw_3.zip Raw NMR data files in .jdx JCAMP-DX data for accessibility format and original JEOL .jdf data reported in the manuscript.\ Includes ^1^H and ^13^C NMR spectra.\ Files are named accord...
