A series of new lipophilic acyclic polyethers containing two carboxylic or hydroxamic acid groups have been prepared. From lipophilic acyclic polyether dicarboxylic acids 2, 9 and 13, the bis(crown ethers) 20–25 were synthesized. From lipophilic acyclic polyether dicarboxylic acids 10–12 and 14, the new macrocyclic diamides 26–32 were prepared in high yields without the use of high dilution techniques
已经制备了一系列含有两个羧酸或异羟肟酸基团的新的亲脂性无环聚醚。从亲脂性的非环状聚醚的二羧酸2,9和13中,双(冠醚)20-25被合成。由亲脂性无环聚醚二羧酸10-12和14可以高收率制备新的大环二酰胺26-32,而无需使用高稀释技术或模板效果。
