  Acylation of alcohols, thiols, and sugars were studied with a variety of Lewis acids, and it was found that Cu- and Sn(OTf)2 are very efficient in catalyzing the reaction under mild conditions. Among these two catalysts, Cu(OTf)2 was preferred because of its lower cost and relatively higher yield of the acylated product. The reaction was studied in several solvents, but CH2Cl2 was preferred. It was

  研究了多种路易斯酸对醇，硫醇和糖的酰化作用，发现Cu-和Sn（OTf）2在温和条件下催化反应非常有效。在这两种催化剂中，Cu（OTf）2是优选的，因为其成本较低并且酰化产物的产率相对较高。在几种溶剂中研究了该反应，但是优选CH 2 Cl 2。还观察到，本方法适用于叔醇的酰化。糖也被酰化，在端基异构中心没有任何差向异构。在此进一步表明，该方法还适用于伯醇或仲醇相对于叔醇的选择性酰化。

  日期：1985.1

  The reaction of olefins with malonamide in the presence of manganese(III) acetate gave 2-buten-4-olides and/or 1H-pyrrol-2(5H)-ones in one-step, short reaction time, and moderate yields. The product distribution can be accounted for in terms of the stabilization of the intermediate carbocation in the oxidation process. The synthetic application and limitation, and the oxidation mechanism for the formations
