The cis novel bisoxazoline ligands L1-L4 have been synthesized through the treatment of new cis dihydroxy diamide with p-toluenesulfonyl chloride in the presence of catalytic quantity of 4--pyridine, and the cis dihydroxy diamide could be achieved from the condensation of the amino alcohols and cis cyclopropane dicarbonyl chloride prepared via oxidation and halogenation from cis-2,2-dimethyl-3-formylcyclopropanecarboxylate with DCC.
我们以蒈醛酸内酯为起始原料，经过氧化反应、酰氯化反应得到顺式环丙烷二酰氯，然后在二环己基碳二亚胺的催化下与相应的氨基醇反应合成了顺式二羟基酰胺，再用对甲苯磺酰氯将羟基活化，最后在二甲氨基吡啶的催化下关环合成顺式双噁唑啉配体L1～L4。
