  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.

  The formation of the 28-membered ring cyclo[(6-amino-6-deoxy-D-galactonic acid)(4)] by cyclisation of a protected open chain fully hydroxylated nylon 6 linear tetramer in modest yield provides the first example of a new class of carbopeptoid-cyclodextrin.

  Hydrogenation of linear omega-azido-pentafluorophenyl esters gives cyclic peptides containing 14-, 21-, 28-, 35-, 56- and 70-membered ring lactams from oligomers derived from epsilon-amino acids in excellent to moderate yields with a lack of racemisation during the cyclisation step.
