The first inverted hemicucurbituril is synthesized in insufficient amount of template during oligomerisation and through its early precipitation.
第一个倒置半葫芦脲在寡聚化过程中由于模板不足而合成不足,并因早期沉淀而形成。

and heterocyclic building blocks can be readily obtained by the hydrogenation of aromatic carbo- and heterocycles. Although a variety of methods have been established to accomplish this transformation for simple arenes, the hydrogenation of aromatic N-heterocycles is less explored. We herein report a diastereoselective arenehydrogenation which was applied to an array of benzo-fused N-heterocycles. A
