Asymmetric total synthesis of naturally occurring γ-butenolide containing [4.4]spiro-tetrahydrofuran lanceolactone A has been reported in this present work. Bimetallic (“Pd–Cu”) cascade cyclization was the crucial reaction employed for the construction of the γ-butenolide framework of the natural product.
