August KekulÃ©'s dream allowed him to correctly propose the presence of one of these structures in benzene.
Esters containing large examples of these structures can be produced in a reaction named for Yamaguchi used in the synthesis of macrolides. Spiro compounds contain multiple examples of these structures linked at a single atom. These structures name a deshielding effect that shifts protons to the 7 to 8 ppm range. Double bonds, triple bonds, and these structures contribute degrees of (*) unsaturation. Torsional strain in these structures results in small ones being unfavorable, while five and six membered examples are particularly stable. Along with being planar and satisfying the 4n + 2 rule, aromatic compounds must contain one of these structures. August KekulÃ©'s dream allowed him to correctly propose the presence of one of these structures in benzene. For 10 points, name these structures found in molecules prefixed with "cyclo-."
