The γ-arylation of substituted silyl-activated butenolides has been studied using a broad scope of unsymmetrical hypervalent diaryliodonium salts via a palladium- or copper-catalysed coupling reaction, yielding interesting reactivity trends. The mild catalytic conditions and coupling partner variability provide access to synthetically useful building blocks toward the pursuit of aryl-lactone containing natural products and allows for facile diversification.
Synthesis of Penta-2,4-dien-1-imines and 1,2-Dihydropyridines by Rhodium-Catalyzed Reaction of N-Sulfonyl-1,2,3-triazoles with 2-(Siloxy)furans

A rhodium(II)-catalyzed reaction of N-sulfonyl-1,2,3-triazoles with 2-(siloxy)furans is reported. Either open-chain penta-2,4-dien-1-imines or cyclic 1,2-dihydropyridines are selectively obtained depending on the ligand on rhodium(II).
Diastereoselective addition of nitro compounds to α,β- unsaturated γ-butyrolactones
Rosso, Giovanni B.,Pilli, Ronaldo A.
, p. 185 - 188 (2007/10/03)
Herein, we report our results on the diastereoselective addition of nitro compounds to α,β-unsaturated γ-butyrolactones, which afforded the corresponding Michael adducts 9-17 in moderate to good yields and good to excellent diastereoisomeric ratio. A one-pot conversion of α,β- unsaturated γ-butyrolactones 7 and 8 to the corresponding trisubstituted keto-γ-butyrolactones 24 and 25 via a tandem Michael-Nef protocol is also described.
