Abstract
The asymmetric total synthesis of phenanthroindolizidine alkaloid (–)-tylophorine was achieved by asymmetric transfer hydrogenation of a cyclic imine. The cyclic imine with a pendant phenanthrene core was synthesized by a TfOH-promoted domino ring-contraction/ring-opening sequence of a cyclobutanol bearing an azide group, which was constructed by a formal [2+2] cycloaddition of a 2′-vinyl-1,1′-biaryl-2-yl ketone enolate. Catalytic asymmetric hydrogenation of the cyclic imine intermediate allowed the late-stage construction of the asymmetric center.
