For the first time iridium catalysis has been used for the synthesis of chiral tetrahydroisoquinolines with excellent yields and high enantioselectivities (see scheme; cod=1,5‐cyclooctadiene, DBU=1,8‐diazabicyclo[5.4.0]undec‐7‐ene). These products are important chiral building blocks for the synthesis of biologically active compounds, in particular alkaloids.
首次铱催化已经被用于具有优异的产率和对映选择性高的手性四氢异喹啉的合成(参见流程; COD = 1,5-环辛二烯,DBU = 1,8-二氮杂双环[5.4.0]十一-7-烯)。这些产物是合成生物活性化合物(特别是生物碱)的重要手性结构单元。
