A procedure for K2S2O8-mediated thiocyanation of α-amino carbonylcompounds has been developed for the synthesis of aromatic thiocyanates. A series of α-amino carbonylcompounds have been investiga...
NH<sub>4</sub>PF<sub>6</sub>-promoted cyclodehydration of α-amino carbonyl compounds: efficient synthesis of pyrrolo[3,2,1-ij]quinoline and indole derivatives
NH4PF6 is an inexpensive, safe, and low-toxicity inorganic salt; it was found to promote the cyclodehydration of α-amino carbonyl compounds in the absence of metal reagents. This simple cyclodehydration strategy enables highly atom-economic formation of pyrrolo[3,2,1-ij]quinoline and indole derivatives, which are significant pharmacophores.
NH 4 PF 6是一种廉价,安全且低毒的无机盐;发现在不存在金属试剂的情况下可促进α-氨基羰基化合物的环脱水。这种简单的环脱水策略使吡咯并[3,2,1- ij ]喹啉和吲哚衍生物具有很高的原子经济性,这是重要的药效团。
