Continuous‐Flow Synthesis of (
<i>R</i>
)‐Tamsulosin Utilizing Sequential Heterogeneous Catalysis
(R)-tamsulosin, three C−N bond formation/cleavage reactions with hydrogen gas over heterogeneous catalysts enabled the efficient construction of the key skeleton. Two different polysilane-modified Pd catalysts were developed for these transformations, which were followed by a deprotection step under homogeneous catalysis to provide tamsulosin in 60 % overall yield in a flow stream.
