• A General and Facile Synthesis of Substituted Furans by Palladium-Catalyzed Cycloisomerization of (<i>Z</i>)-2-En-4-yn-1-ols
  作者：Bartolo Gabriele、Giuseppe Salerno、Egidio Lauria

  日期：1999.10.1

  A general and facile synthesis of furans, based on Pd(II)-catalyzed cycloisomerization of (Z)-2-en-4-yn-1-ols, is described. Cycloisomerization reactions are carried out at 25-100 degrees C in the presence of a very simple catalytic system, consisting of K2PdI4, under essentially neutral conditions. This new methodology is very versatile and can be applied to the synthesis of a variety of substituted furans, including particularly fragile, naturally occurring furans such as rosefuran. Efficient synthetic approaches for the regioselective synthesis of suitably substituted (Z)-2-en-4-yn-1-ols have been developed.

  A disinfectant system, comprising a first aqueous composition having a peracid reactant compound that is either a peroxide compound or an organic acid compound, and a second aqueous composition comprising the peracid reactant compound not selected for the first composition. Each composition is applied separately to, and combined upon, a surface to form a reaction layer, within which a peracid is formed in situ, disinfecting the surface. The compositions can have a flash point, surface tension, and vapor pressure compatible for application as a spray, mist, aerosol, or fog, and can be formulated with an alcohol blend that enables the reaction layer to completely evaporate from the surface after disinfection is complete. In use, the disinfectant systems disclosed herein have up to 99.999% antimicrobial efficacy against organism such as Staphylococcus aureus, Pseudomonas aeruginosa, and Candida auris.

  A tandem reaction of 4-(1-acetoxyallyl)-1-sulfonyl-1,2,3-triazole including formation of α-imino rhodium carbene, 1,2-migration of an acetoxy group and six electron electrocyclic ring closure was reported. The migration of the OAc group with excellent chemoselectivity was the crucial process, leading to the formation of 1,2-dihydropyridine specifically in up to 90% yield. Several transformations of
