Enantioselectivehydrogenation of a broad spectrum of N‐, O‐, and S‐containing aromatic benzoheterocycles or nonaromatic unsaturated heterocycles has been realized by using an Ir/SpinPHOX (SpinPHOX=spiro[4,4]‐1,6‐nonadiene‐based phosphine‐oxazoline) complex as the catalyst, affording an array of the corresponding chiral benzoheterocycles (30 examples) with excellent enantioselectivities (>99 % ee in
