  • Microwave-accelerated, palladium-catalyzed carbonylative cyclization reactions of 2-iodophenol with alkynes — Rapid and efficient synthesis of chromen-2-one derivatives
    作者:Hong Cao、Wen-Jing Xiao

    日期:2005.6.1
    Rapid palladium-catalyzed carbonylative cyclization reactions of 2-iodophenol with various alkynes have been carried out by the use of commercially available molybdenum hexacarbonyl as a convenient and solid carbon monoxide source. The reactions were conducted at 160 °C for 30 min with microwave heating in the presence of DIEA and DMAP in 1,4-dioxane, and afford the corresponding chromen-2-one derivatives

    o-Iodophenols and o-iodoaniline derivatives react with terminal alkynes under 1 atm of CO in the presence of pyridine and catalytic amounts of Pd(OAc)2 to generate coumarins and 2-quinolones, respectively, as the only products. Terminal alkynes bearing alkyl, aryl, silyl, hydroxyl, ester and cyano substituents are effective in these processes affording the desired products in moderate yields. The formation

  • [Pd(PPh3)2(saccharinate)2]—general catalyst for Suzuki–Miyaura, Negishi cross-coupling and C–H bond functionalization of coumaryl and pyrone substrates
    作者:Parin Shah、M. Dolores Santana、Joaquín García、J. Luis Serrano、Minal Naik、Suhas Pednekar、Anant R. Kapdi
    DOI:10.1016/j.tet.2012.12.030
    日期:2013.2
    The potential of complex [Pd(PPh3)(2)(saccharinate)(2)] 1 in catalyzing Suzuki-Miyaura cross-coupling of 4-halo and 4-bromomethyl coumaryl and pyrone substrates with different aryl boronic acids has been explored. Excellent yields of the desired products are obtained in competitive reaction time and under relatively mild conditions. Negishi cross-coupling of 4-coumaryl tosylate with aryl and allcylzinc reagents has also been performed with good yields of the cross-coupled products obtained in most cases. Intramolecular C-H bond functionalization of coumaryl ethers also furnished very high yields of synthetically attractive tetracyclic ring systems exhibiting the potential of I as a powerful catalyst in synthetically important reactions.
