The total synthesis of natural lignans 5′-methoxyyatein (1), 5′-methoxyclusin (2), and 4′-hydroxycubebinone (3), in racemic form, has been achieved by a newly developed strategy, wherein lithium naphthalenide induced decyanation was employed as a key operation to establish the essential trans configuration of the butyrolactone ring.
