the E- and Z-isomers of 1 in racemic form as the major constituents. Among them, it is the (R,Z)-isomer, which exhibits the most favorable musk character and by far the lowest threshold; for these superior olfactory properties, pure (R,Z)-1 has recently been commercialized too. We present an efficient route to this precious compound based on an iron-catalyzed cross coupling reaction, a molybdenum-catalyzed
Muscenone ®是由所述的混合物的一种有价值的香料成分ë -和ž -异构体的1外消旋形式作为主要组分。其中,(R,Z)-异构体表现出最有利的麝香特性,迄今为止阈值最低。由于具有这些优越的嗅觉特性,最近也已将纯净的(R,Z)-1商业化。我们基于铁催化的交叉偶联反应,形成大环的钼催化的炔烃复分解反应以及镍催化的半氢化反应,提出了一种有效的途径,以这种贵重的化合物。
