ng metathesis reactions to install the macrocycle‐fused butenolide ring and a tandem allylboration/lactonization to build the α‐methylene‐γ‐lactone. Our syntheses have enabled the determination of the hitherto unknown stereochemical configurations of this family of natural products. Preliminary tests of structure–activity relationships were conducted with four natural ovatodiolides and three analogues
The invention relates to the field of polymers and olefin polymerization, and more specifically olefin metathesis polymerization. The invention provides regioregular alternating polymers and methods of synthesizing such polymers.

Sulfonyl chlorides are inexpensive reactants extensively explored for functionalization, but never considered for radical hydrosulfonylation of alkenes. Herein, we report that tris(trimethylsilyl)silane is an ideal hydrogen atom donor enabling highly effective photoredox‐catalyzed hydrosulfonylation of electron‐deficient alkenes with sulfonyl chlorides. To increase the generality of this transformation
