Catalytic conjugate additions of heteroarenes to β,β-disubstituted enones are reported. Additions of a range of heteroarene nucleophiles, including furans, indoles, a pyrrole, and a thiophene, to a variety of β,β-disubstituted enones occur to form the corresponding ketone products containing heteroarylated, all-carbon quaternary centers in up to 90% yield. These reactions occur under mild reaction
报道了杂芳烃向β,β-二取代的烯酮的催化共轭加成。发生一系列杂芳烃亲核试剂,包括呋喃,吲哚,吡咯和噻吩,形成各种β,β-二取代的烯酮,以形成相应的酮产物,该产物含有高达90%的杂芳基全碳四元中心屈服。这些反应在低负载的三氟甲磺酸铋的存在下,在温和的反应条件下发生。
