Csenki, Janos T.; Meszaros, Adam; Gonda, Zsombor; Novak, Zoltan published the article 《Stereoselective Direct N-Trifluoropropenylation of Heterocycles with a Hypervalent Iodonium Reagent》. Keywords: azole trifluoroisopropenyl iodonium trifluoromethanesulfonate diastereoselective trifluoropropenylation; trifluoropropenyl azole preparation; Michael addition; enamines; iodonium salt; nitrogen heterocycles; trifluoromethyl.They researched the compound: 2,6-Dichloropurine( cas:5451-40-1 ).Name: 2,6-Dichloropurine. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:5451-40-1) here.
The availability and synthesis of fluorinated enamine derivatives such as N-(3,3,3-trifluoropropenyl)heterocycles are challenging, especially through direct functionalization of the heterocyclic scaffold. Herein, a stereoselective N-trifluoropropenylation method based on the use of a bench-stable trifluoropropenyl iodonium salt was described. This reagent enabled the straightforward trifluoropropenylation of various N-heterocycles under mild reaction conditions, providing trifluoromethyl enamine type moieties with high stereoselectivity and efficiency.
