Each adduct of α-terpinene with p-quinone and 1,4-naphthoquinone in Ac2O/Et3N at 180 °C gives two aromatic products, one of which had a distinctive smell formed by the loss of an ethylene group. Here, we report the crystal structure of (1RS, 4RS)-1-isopropyl-4-methyl-1,4-dihydro-1,4-ethanoanthracene-9,10-diyl diacetate. It is crystallised in an orthorhombic space group, Pbca, with cell dimensions a
在 180 °C 的 Ac2O/Et3N 中,α-
萜品烯与对醌和
1,4-萘醌的每种加合物都会产生两种芳香族产物,其中一种具有独特的气味,是由于失去了一个
乙烯基而形成的。在这里,我们报告了 (1RS, 4RS)-1-isopropyl-4-methyl-1,4-dihydro-1,4-ethanoanthracene-9,10-diyl diacetate 的晶体结构。它在正交空间群 Pbca 中结晶,晶胞尺寸 a = 10.2899(7), b = 19.7804(9), c = 19.7519(8) Å 和 Z = 8。根据其 NMR 和 X 射线衍射数据,异丙基和
乙酸酯基团缓慢旋转。
