抜粋

By attaching bulky substituents at the bay region of di(spiroacridan)- substituted dihydrophenanthrene 1a, the prestrained C9-C10 bond in the dihydrophenanthrene (DHP) skeleton of 1c-1e is expanded from 1.634(2) to 1.649(3)-1.652(6) Å, which demonstrates the bond expansion through remote steric effects. Twisting deformation of the DHP skeleton is the key to transfer the steric bulkiness from the C4/C5 positions to cause the additional strain in the C9-C10 bond.
