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.
