  摘要：

  在丙酮中，在二甲氧基丙烷和托西酸的作用下，D-半乳糖酸-1,4-内酯可分别生成20%和78%的甲基2,3:5,6-二-O-异亚丙基-D-半乳糖酸酯6（仅C-4上的次羟基未受保护）和甲基2,3:4,5-二-O-异亚丙基-D-半乳糖酸酯5（仅C-6上的主羟基未受保护）。1,4-二脱氧-1,4-亚氨基-D-葡萄糖醇16（一种吡咯烷）的合成以及6-叠氮-6-脱氧-D-半乳糖酸-1,4-内酯22的高效制备都说明了这种易得中间体的价值。将22转化为七元半乳糖内酰胺21（一种四羟基己内酰胺）可得到羟基化尼龙聚合物。半乳糖内酰胺21对多种糖苷酶没有明显的抑制作用。22与三氟甲磺酸酐反应可生成两种外消旋5-（叠氮甲基）四氢呋喃-2-羧酸酯，它们可作为两种系列碳青霉烯类药物的起始原料

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

  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.

  Treatment of D-galactono-1,4-lactone with dimethoxypropane in acetone in the presence of tosic acid forms methyl 2,3:5,6-di-O-isopropylidene-D-galactonate 6 (with only the secondary hydroxy group at C-4 unprotected) and methyl 2,3:4,5-di-O-isopropylidene-D-galactonate 5 (with only the primary hydroxy group at C-6 unprotected) in yields of 20% and 78%, respectively. The value of such easily accessible intermediates is illustrated by the synthesis of 1,4-dideoxy-1,4-imino-D-glucitol 16 (a pyrrolidine), and for the efficient preparation of 6-azido-6-deoxy-D-galactono-1,4-lactone 22. The conversion of 22 to a seven-membered galactonolactam 21 (a tetrahydroxycaprolactam) may provide access to hydroxylated nylon polymers. The galactonolactam 21 has no significant inhibitory effect on a number of glycosidases. Reaction of 22 with triflic anhydride gives two epimeric 5-(azidomethyl)tetrahydrofuran-2-carboxylates which provide starting materials for two series of carbopeptoids, one of which probably has a helical structure and the other a structure reminiscent of a β-turn.
