建立了用级联反应高效合成2h -3-亚硝基铬的方法。以市售的邻溴苯甲醛和β-亚硝基苯乙烯为原料，以非水合硫化钠为廉价硫源，在不添加任何过渡金属催化剂或添加剂的情况下，合成了各种具有高官能团耐受性的取代硫代铬。
An efficient synthesis of 2H-3-nitrothiochromenes via a cascade reaction was established. Starting from commercially available o-bromobenzaldehydes and β-nitrostyrenes with sodium sulfide nonahydrate as an inexpensive sulfur source, various substituted thiochromenes were synthesized with high functional group tolerance without any added transition metal catalyst or additive.
