Torsional strain in these structures results in small ones being unfavorable, while five and six membered examples are particularly stable.
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-."
