The other side: A convergent totalsynthesis of peloruside A (1) is described. The key strategic features are a diastereoselective lactonization to generate a C5–C9 valerolactone from the C2‐symmetric ketone 3, and a relay ring‐closing metathesis reaction to produce a dehydrovalerolactone 2. A new isomer of 1, the valerolactone isopeloruside A (iso‐1), was identified. MOM=methoxymethyl.
