7331-52-4, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 7331-52-4, molcular formula is C4H6O3, introducing its new discovery.
Process for producing optically active gamma-butyrolactone
This invention provides a novel process for producing optically active 3-hydroxy-gamma-butyrolactone in a short step, which is superior economically and in efficiency and industrially suitable by using a starting material which is inexpensive and easily available and reagents easy to handle. This invention relates to a process for producing optically active 3-hydroxy-gamma-butyrolactone represented by formula I: 1wherein the symbol * means an asymmetric carbon atom, which comprises hydrogenating an optically active 4-substituted oxy-3-hydroxybutyrate represented by formula II: 2wherein R1 represents a C1-4 lower alkyl group, R2 represents a protective group for a hydroxyl group deprotected by hydrogenation with a heterogeneous hydrogenation catalyst, and the symbol * has the same meaning as defined above, in the presence of a heterogeneous hydrogenation catalyst and an acidic substance followed by deprotection and simultaneous ring closure thereof.
Because enzymes can increase reaction rates by enormous factors and tend to be very specific, 7331-52-4, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 7331-52-4
