A new class of strigolactoneanalogues has been synthesized. They differ from known molecules, both of natural and synthetic origin, in two main features. The conjugated system extends from the enol ether bridge to the A ring, the B ring is a heterocycle while the C ring is a cyclic ketone instead of a γ-lactone. The key step of the synthesis is a Nazarov cyclization on activated substrates. Bioassays
