asymmetric conjugate addition to γ,δ-unsaturated β-dicarbonyl compounds was developed. With a chiral diene–rhodium(I) μ-chloro dimer as the catalyst in toluene/H2O, asymmetric conjugate arylation of γ,δ-unsaturated β-dicarbonyl compounds with arylboronic acids proceeded in high efficiency with excellent enantioselectivities. The generated β-dicarbonyl products are versatile chiral synthons, which can
研发了向γ,δ-不饱和β-二羰基化合物中的第一个催化不对称共轭加成物。用手性二烯-铑(I)μ-氯二聚体作为甲苯/ H 2 O的催化剂,γ,δ-不饱和β-二羰基化合物与芳基硼酸的不对称共轭芳基化反应高效进行,具有出色的对映选择性。生成的β-二羰基产物是通用的手性合成子,可以容易地转化为多种重要的手性结构。
