چکیده

A gold-catalyzed intramolecular coupling of diazo compounds to produce cyclic olefins has been well established. The medium and large sized membered olefins were obtained in moderate to good yields. Notably, the Z/E selectivity of the olefins highly depended on the ring size. Furthermore, this investigation indicated that the structure of the phosphorous ligand binding to the gold centre played a vital role in the reaction efficiency. Also, high dilution of the reaction mixture is not needed.

Intramolecular additions of alcohols and carboxylic acids to inert olefins catalyzed by silver(I) triflate.

[reactions: see text] Intramolecular additions of hydroxyl or carboxyl groups to inert olefins catalyzed by simple silver(I) triflate are described. Good to excellent yields can be obtained for a range of substrates under relatively mild conditions. This reaction represents one of the simplest methods to construct cyclic ethers or lactones.

Synthesis of oxygen-containing heterocyclic compounds based on the intramolecular O–H insertion and Wolff rearrangement of a-diazocarbonyl compounds

The addition products of Ti(IV)-enolate derived from b-keto a-diazo carbonyl compound to ketones or a,b-unsaturated compounds were subjected to Rh2(OAc)4-catalyzed and photo-induced diazo decomposition. The Rh2(OAc)4-catalyzed reaction afforded intramolecular O–H insertion products, while the photo-induced reaction gave Wolff rearrangement/intramolecular nucleophilic addition products. The tran...

Addition of heterocycles to electron deficient olefins and alkynes catalyzed by gold(III)

A gold(III)-catalyzed hydroarylation of different olefins is reported here. AuCl3 works as an excellent catalyst to mediate reactions between various heterocycles and electron deficient olefins and alkynes under mild conditions. This gold(III)-based method tolerates different functional groups such as aldehyde, carboxylic acid, nitrile, and is highly efficient. We have shown that some of these ...

Along with the intramolecular C–H insertion reactions by carbenoids, intramolecular N–H insertion reactions of α-diazocarbonyl substrates catalyzed by metal complex have received considerable attention in recent years. This type of insertion reaction has been shown to be a mild and efficient route to 4-, 5-, and 6-membered aza rings. A frequently cited example of this powerful approach is the M...
