The first totalsynthesis of solanacol, a member of the strigolactone family, features ring‐closing metathesis, enzymatic kinetic resolution, and atom‐transfer radical cyclization. This defines the stereostructure of the natural product. The best hormonal activity is revealed by an acetylated derivative at O4 (see scheme).
A new general access to A‐ring aromatic strigolactones, a new class of planthormones, has been developed. The key transformations include in sequence ring‐closing metathesis, enzymatic kinetic resolution and a radical cyclization with atom transfer to install the tricyclic ABC‐ring system. The activity as planthormones for the inhibition of shoot branching in pea of various analogues synthesized
