Enyne metathesis is one of the major classes of metathesis that redistributes the 蟺 systems of an alkene and an alkyne to form a 1,3-diene. One of the inherent selectivity problems in enyne metathesis originates from the two possible addition modes of a metal alkylidene to alkynes, which ...

The individual dominoes symbolize elementary bond‐forming events by which simple alkene and alkyne building blocks are processed in tandem to form products of extended conjugation and polycyclic systems. Many enyne‐metathesis‐based tandem reactions developed and applied to the synthesis of natural and ...
