, p. 79 - 85 (2000)
Chiral bishomodiazacalix[4]arenes containing amino acid residues were prepared. The 1H and 13C nmr spectra indicated that the macrocycles preferably adopted a cone conformation, which suggested that the cyclophane moiety was in a chi

Decahomotetrathiacalix[6]arenes were conveniently prepared from the 2:2 cyclization reactions of bis(chloromethyl)phenol-formaldehyde trimers with 1,2-ethanedithiol in high yields. In contrast, the similar reactions of the trimers with 1,3-propanedithiol
