1,4-Conjugate addition of allyltrimethylsilane to α,β-unsaturated ketones
Yadav,Reddy,Sadasiv,Satheesh
, p. 9695 - 9697 (2002)
α,β-Unsaturated ketones smoothly undergo conjugate addition with allyltrimethylsilane in the presence of a catalytic amount of elemental iodine under very mild and convenient conditions to afford the corresponding Michael adducts in high yields with high
First synthesis of α,β-unsaturated lactones with high diversity through the Passerini reaction and ring-closing metathesis (RCM)

experimental part, p. 4335 - 4344 (2011/09/15)
A new class of α,β-unsaturated pyran-2-carboxamides was easily accessed by a multicomponent reaction (MCR), followed by a ring-closing metathesis (RCM) using a ruthenium catalyst. In the first step, α-acyloxy carboxamides with two terminal double bonds were formed from terminal unsaturated carboxylic acids, allyl ketones, and isocyanides (Passerini reaction, P-3CR). A new class of α,β-unsaturated pyran-2-carboxamides was easily accessed by amulticomponent reaction (MCR), followedby a ring-closing metathesis (RCM) using a ruthenium catalyst.
Catalytic enantioselective Hosomi-Sakurai conjugate allylation of cyclic unsaturated ketoesters
Shizuka, Manami,Snapper, Marc L.
