New synthetic routes to the reduction products of several collagen cross-links and cross-link precursors are described. By the use of these routes hydroxynorleucine, 5,6-dihydroxynorleucine, hydroxylysinonorleucine and hydroxylysinohydroxynorleucine can be synthesized via one common synthetic intermediate. The synthetic routes provide a convenient source of these unusual amino acids, as well as confirming the structure of hydroxylysinohydroxynorleucine and the other lysine-derived residues found in borohydride-reduced collagens.
本文描述了几种胶原蛋白交联产物和交联前体还原产物的新合成路线。通过这些路线,羟基正亮氨酸、5,6-二羟基正亮氨酸、羟赖氨酰正亮氨酸和羟赖氨酰羟正亮氨酸可以通过一个共同的合成中间体进行合成。这些合成路线为这些特殊氨基酸提供了便利的来源,同时也证实了羟赖氨酰羟正亮氨酸以及在硼氢化钠还原的胶原蛋白中发现的其他赖氨酸衍生残基的结构。
