Li, Lifan; Song, Xuyan; Qi, Mei-Fang; Sun, Bing published the artcile< Weak Bronsted base-promoted photoredox catalysis for C-H alkylation of heteroarenes mediated by triplet excited diaryl ketone>, SDS of cas: 93-60-7, the main research area is alkylated heteroarene regioselective preparation; heteroarene ether CH alkylation photoredox catalysis.
A weak Bronsted base-promoted photoredox catalysis had been developed for the direct C-H α-alkylation of heteroarenes with cyclic and acyclic ethers. The high efficiency of this strategy was demonstrated by the mild reaction conditions, broad substrate scope, economical reagents and high regioselectivity. With air as the sole oxidant, a set of alkylated heteroarenes were accessed smoothly. This strategy was also applied for late-stage functionalization of valuable vitamin E nicotinate and loratadine.
Tetrahedron Letters published new progress about Alkylation catalysts. 93-60-7 belongs to class pyridine-derivatives, and the molecular formula is C7H7NO2, SDS of cas: 93-60-7.
