arylnaphthalene or aryldihydronaphthalene lactones selectively as determined by choice of reaction solvent. This constitutes the first report of an entirely selective formation of arylnaphthalene lactones utilizing DDA reactions of styrene-ynes. The synthetic utility of the DDA reaction is demonstrated by the synthesis of taiwanin C, retrohelioxanthin, justicidin B, isojusticidin B, and their dihydronaphthalene
根据反应溶剂的选择,进行分子内脱氢-狄尔斯-阿尔德 (DDA) 反应,选择性地提供芳基萘或芳基二氢萘内酯。这构成了利用苯乙烯-炔的 DDA 反应完全选择性地形成芳基萘内酯的第一份报告。DDA 反应的合成效用通过 taiwanin C、retrohelioxanthin、justicidin B、isojusticidin B 及其二氢萘衍生物的合成得到证明。介绍了化学位移分配的计算方法,可以区分区域异构木脂素。
