The total synthesis of the diterpene hedychilactone B 1 is reported. The exo adduct 4x, the major product of the stepwise [4+2] cycloaddition of the diene 2 and the allenoate 3, has been converted into 1 via 7 steps, among them a key nonconjugative hydrolysis of a gamma-methylene silyl enol ether and an E-selective olefination.
