A protocol for the introduction of spiro[4.5] lactone straps onto the Tröger’s base scaffold has been developed. The conversion was found to be most efficient when an appropriate carboxylic acid derivative reacted with 5,6,11,12-tetrahydrodibenzo[b,f][1,5]diazocines. Whilst phthaloyl dichloride was the main strap-forming precursor used, other 1,2-unsaturated dicarboxylic acids could be used in the presence of N,N′-dicyclohexylcarbodiimide.
已开发出将螺[4.5]内酯带引入 Tröger 基础支架上的方案。当适当的羧酸衍生物与5,6,11,12-四氢二苯并[b,f][1,5]重氮辛反应时,转化效率最高。虽然邻苯二甲酰二氯是所用的主要条带形成前体,但在 N,N'-二环己基碳二亚胺存在下也可以使用其他 1,2-不饱和二羧酸。
