Sequence‐controlled oligomers of cyclic imino ethers were synthesized by the one‐pot multi‐stage feeding method. Selective formation of the sequence was clearly demonstrated by equimolar reactions between the monomers and 1:1 adducts of an initiator with the monomers. Efficiency of the sequence control is determined by the difference of reactivities of the active ends. A new general prerequisite to synthesize a well‐defined sequence by multi‐stage oligomerization was proposed.
