Abstract
The Michael addition of bis(nitrogen or sulfur) nucleophiles to divinyl sulfone provides the corresponding macrocyclic adducts in good yields. The structures of some new macrocyclic sulfones are established by X-ray crystallographic analysis and NMR spectroscopy. The subsequent cleavage of benzyl or tosyl groups yields the unprotected macrocyclic sulfones. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
