Aspernomine, a natural product isolated from the fungus Aspergillus nomius, was found to be an antiinsectan (it protects against predation by insects). (J. Am. Chem. Soc. 2012, 134, 8078–8081): Two of the six-membered rings are represented in chair conformations. The connection between these two rings is analogous to that in trans-decalin cis-decalin The aromatic ring is in an axial position equatorial position Consider the six-carbon acyclic substituent bound to one of the bridgehead carbons. What is its relationship (axial or equatorial) to each of the chairs? Branch is equatorial to A chair but axial to B chair. Branch is axial to both A and B chairs. Branch is axial to A chair but equatorial to B chair. Branch is equatorial to both A and B chairs. What is the approximate dihedral angle between the two methyl groups directly bound to the chairs? 180o 60o 90o 0o
