Ito,Nagai,Ohba,Sone
, p. 1121 - 1128 (2000)
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
Syntheses of chiral calixarene analog incorporating amino acid residues: Molecular recognition for a racemic ammonium ion by the macrocycles
Ito, Kazuaki,Kida, Atsushi,Ohba, Yoshihiro,Sone, Tyo
, p. 1221 - 1222 (2007/10/03)
Chiral calixarene analog incorporating amino acid residues into macrocyclic rings was prepared. The macrocycles form a chiral concave, which is induced by the chiral transmission from the amino acid to the phenol-formaldehyde tetramer unit through the hyd
