Mesoporous silica grafted with a tertiary amine was used as a basic nanocatalyst to promote in confined medium the enantioselective cascade rearrangement of enediynes based on the phenomenon of memory of chirality; the multi-substrates recyclable catalytic reagent could easily be recovered by simple filtration, and reused without any decrease in activity even when changing the solvent.
基于手性记忆现象,使用接枝了叔胺的介孔
二氧化硅作为碱性纳米催化剂,在密闭介质中促进烯二炔的对映选择性级联重排;这种多基质可回收催化试剂可通过简单过滤轻松回收,即使更换溶剂也不会降低活性。
