Synthesis of Cinnamides via Amidation Reaction of Cinnamic Acids with Tetraalkylthiuram Disulfides Under Simple Condition

A facile and efficient methodology for the synthesis of cinnamides has been achieved under metal- and additive-free conditions. This method allows the efficient C–N cross-coupling of diverse cinnamic acids with tetraalkylthiuram disulfides through a simply mixing operation in 1,2-dichloroethane at 100 °C. The protocol provides a direct approach to cinnamides and is featured with readily available starting materials and broad substrate scope, which shows its practical synthetic value in organic synthesis.

Visible-light-promoted oxidation/condensation of benzyl alcohols with dialkylacetamides to cinnamides

Oxidative cross-coupling reactions of benzyl alcohols with N,N-dialkylacetamides were developed only employing oxygen as the terminal oxidant, efficiently providing a new, novel protocol for the construction of multifunctionalized cinnamides with the synergistic effects of KOH, organic photocatalyst eosin Y, and visible light irradiation at room temperature. A broad substrate scope and mild reaction conditions are the prominent features of this transformation.

Chemoselective α,β-Dehydrogenation of Saturated Amides

We report a method for the selective α,β-dehydrogenation of amides in the presence of other carbonyl moieties under mild conditions. Our strategy relies on electrophilic activation coupled to in situ selective selenium-mediated dehydrogenation. The α,β-unsaturated products were obtained in moderate to excellent yields, and their synthetic versatility was demonstrated by a range of transformations. Mechanistic experiments suggest formation of an electrophilic SeIV species.

Oxidative coupling of alkenes with amides using peroxides: Selective amide C(sp3)-H versus C(sp2)-H functionalization

A new oxidative coupling of unactivated terminal alkenes with amides using peroxides is described, in which mono- and difunctionalization of alkenes are selectively achieved. In this reaction with amides, the chemoselectivity toward the functionalization of the C(sp3)-H bonds adjacent to the nitrogen atom or the functionalization of the carbonyl C(sp2)-H bonds across alkenes relies on the reaction conditions.

Copper-catalyzed oxidative coupling of carboxylic acids with formamides for the synthesis of α,β-unsaturated amides

A novel and efficient protocol for the synthesis of α,β- unsaturated amides has been developed using catalytic amount of Cu(OAc) 2 and TBHP as an available oxidant. Oxidative coupling of various unsaturated carboxylic acids with N,N-disubstituted formamides was examined to furnish the desired products in good yields.

Oxygen and base-free oxidative heck reactions of arylboronic acids with olefins

A mild and efficient protocol for palladium-catalyzed oxidative Heck reactions of arylboronic acids with both electron-rich and -deficient olefins is described. In contrast to the normal oxidative Heck coupling, this new method works in the absence of a base, oxygen, or other external oxidants. With a wide variety of substrates tolerated, the method broadens the scope of palladium-catalyzed coupling reactions. Copyright

Mizoroki-Heck type arylation of alkenes using aroyl chlorides under base-free conditions

The Mizoroki-Heck type arylation of alkenes with aroyl chlorides accompanied by decarbonylation efficiently proceeds in the presence of a palladium catalyst system, PdCl2(PhCN)2/(PhCH 2)Bu3NCl, even without adding any base. The products can be isolated by a very simple procedure.
