There is an Asian legend in which a fish climbs over a waterfall and turns into a dragon. In this study, domino double spirocyclization occurred over the high energy barrier arising from the aromaticity. The key reagents were Ag salt, N‐iodosuccinimide (NIS), and 1,1,1,3,3,3‐hexafluoro‐2‐propanol (HFIP) solvent, whose names are hidden in the picture. These reagents transformed simple molecules into complex 3D architectures. More information can be found in the Communication by Hiromasa Yokoe, Naoki Kanoh et al.

有亚洲传说，一条鱼爬过瀑布变成一条龙。在这项研究中，多米诺骨牌双螺环化发生在由芳香性引起的高能垒之上。关键试剂为银盐，N-碘代琥珀酰亚胺（NIS）和1,1,1,3,3,3-六氟-2-丙醇（HFIP）溶剂，其名称隐藏在图片中。这些试剂将简单分子转化为复杂的3D体系结构。有关更多信息，请参见Hiromasa Yokoe的通讯，Naoki Kanoh等人的文章。
