A concise, flexible, and linear approach has been devised for the total synthesis of the resorcinylic acid lactones (S)-zearalenone (2) and (R)-de-O-methyllasiodiplodin (4) by using a Stille cross-coupling strategy. The other key steps of the synthesis include a ring-closing metathesis (RCM), a chemoselective reduction of an α,β-unsaturated ketone, and a transesterification reaction.

Macrolide (R)-de-O-methyllasiodiplodin (1), discovered to be a potent nonsteroidal antagonist of the mineralocorticoid receptor (MR), was synthesized via an efficient method and evaluated for MR antagonistic activity together with its analogs. Among all the tested compounds, compounds 18a, 18b and 18c, exhibited more potent antagonistic activity against MR with IC50 values ranging from 0.58 to 1.11 μM. Generally, it was obviously demonstrated that acetylation at phenolic hydroxyl groups and the ring size in analogs of 1 were very important for MR antagonist activity.

The asymmetric synthesis of both enantiomers of methyl lasiodiplodin is described. The chiral centers were created in the very last steps of the synthesis by asymmetric induction of a chiral sulfoxide group.
