A novel difunctionalization reaction is described. It uses N-trifluoromethylthio-4-nitrophthalimide as the reagent, which serves as both the nitrogen and SCF3 sources. In the presence of DABCO (1,4-diazabicyclo[2.2.2]octane), the nitrogen and SCF3 groups can be incorporated into α,β-unsaturated carbonyl compounds easily and give versatile β-amino ketones and esters in good yields. This difunctionalization
描述了新的双官能化反应。它使用N-三氟甲基硫基-4-硝基邻苯二甲酰亚胺作为试剂,既用作氮源,又用作SCF 3源。在DABCO(1,4-二氮杂双环[2.2.2]辛烷)的存在下,氮和SCF 3基团可以轻松地掺入α,β-不饱和羰基化合物中,并以良好的收率得到通用的β-氨基酮和酯。此difunctionalization反应设有反应条件温和,高原子经济性,并且α-SCF高效访问3个氨基酸。
