摘要:The inventive subject matter relates to novel processes for making an epoxy alcohol from an aldehyde, comprising the steps of: (a) adding (i) an organozinc compound or (ii) divinylzinc compound and an diorganozinc compound to said aldehyde in the presence of a first catalyst to form an allylic alkoxide compound; and (b) epoxidizing said allylic alkoxide compound in the presence of an oxidant and a second catalyst.

摘要:The present invention is directed to aspartic protease inhibitors. Certain aspartic protease inhibitors of the invention can be represented by the following structural formula or a pharmaceutically acceptable salt thereof. The present invention is also directed to pharmaceutical compositions comprising the disclosed aspartic protease inhibitors. The present invention is further directed to methods of antagonizing one or more aspartic proteases in a subject in need thereof, and methods for treating an aspartic protease mediated disorder in a subject using the disclosed aspartic protease inhibitors.

摘要:A process for the selective production of acetaldehyde by vapor phase reaction of acetic acid over a hydrogenating catalyst composition to form acetaldehyde is disclosed and claimed. In an embodiment of this invention reaction of acetic acid and hydrogen over platinum and iron supported on silica selectively produces acetaldehyde in a vapor phase at a temperature of about 300° C.

摘要:A catalyst system for the conversion of synthesis gas in a single stage to liquid hydrocarbons comprises (a) a copper-containing alcohol synthesis catalyst, (b) an iron-containing modifier for the alcohol synthesis catalyst to promote the formation of hydrocarbons, and (c) a metallosilicate wax cracking catalyst. The alcohol synthesis catalyst (a) can contain thorium, zinc, uranium or zirconium in addition to the copper. The iron-containing modifier (b) can contain an iron-containing zeolite such as ferrierite or an inorganic support containing ferrous or ferric ions. The metallosilicate can be a zeolite or gallosilicate. The zeolite can have a pore diameter of at least 5 Angstroms and can have the faujasite structure. A Group VIIIA metal e.g., Pd may be incorporated on the zeolite to suppress coke formation. A hydrocarbon product from the conversion can be obtained containing at least 70 percent by weight of hydrocarbons in the range C3 to a boiling point of 340 DEG C., and less than 10 percent by weight of methane.
