A readily available cyclic carbamate 1 functions as a general precursor to a range of functionalized piperidine products via a new Pd‐catalyzed annulation strategy. An asymmetric catalytic variant provides a rapid and efficient means to access these heterocycles with high to excellent levels of enantiocontrol. Finally, these richly functionalized compounds are amenable to further chemoselective elaboration
