  Towards hydroxylated nylon 6: linear and cyclic oligomers from a protected 6-amino-6-deoxy-d-galactonate––a novel class of carbopeptoid-cyclodextrin (CPCD)

  摘要：

  Circular dichroism studies on a series of linear oligomers derived from a protected 6-amino-6-deoxy-D-galactonate (an epsilon-amino acid) indicated a predisposition to form a rigid structure in solution, which is comparable to a beta-sheet composed Of L-amino acids; in contrast, a diastereomeric allonate series provided no evidence for secondary structure. A linear tetramer was cyclised to a 28-membered ring lactam in modest yield, which on deprotection formed a class of macrocycle with structural features of both a cyclic peptide and a cyclodextrin.
