Abstract
Belt-shaped molecules of the general type 2 containing up to five benz ene ring units (cf. 37) have been synthesized by macrocyclisation reac tions of ribbon-shaped precursors. An intermolecular cyclization step generates the macroheterocycles 38 and 40. The fourfold-bridged cyclop hane 36 are prepared by intra- and intermolecular cyclization reaction s. The X-ray structure analyses of 14, 16, 22, 23, 28, and 36 show S-s haped conformations of the molecules.
