In heterogeneous catalysis, the catalyst is in a different phase from the reactants. SDS of cas: 117752-88-2, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 117752-88-2, name is (R)-3-Amino-g-butyrolactone hydrochloride. In an article，Which mentioned a new discovery about 117752-88-2

Synthesis of enantiomerically pure beta-amino-alpha-methylene-gamma-butyrolactones by way of ozonolysis of aromatic alpha-amino acids

The (R) and (S) isomers of beta-amino-alpha-methylene-gamma-butyrolactone hydrochloride (4-amino-dihydro-3-methylene-2(3H)-furanone hydrochloride) have been synthesized from (R)- and (S)-tryptophan, respectively.A key step is the ozonolysis of N,O-diacetyl-2-amino-3-(3′-indolyl)-1-propanol. (S)-beta-Amino-alpha-methylene-gamma-butyrolactone hydrochloride has been synthesized also by an analogous route starting with (S)-phenylalanine.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 117752-88-2, help many people in the next few years.SDS of cas: 117752-88-2

Single Step Conversion of Chiral Carnitine and Derivatives into (S)- and (R)-beta-Substituted-gamma-Butyrolactones

This paper describes an efficient single step transformation of chiral carnitine and carnitine derivatives into stereoisomerically pure (S)- and (R)-beta-substituted-gamma-butyrolactones, obtained by intramolecular nucleophilic displacement. (S)- Or (R)-carnitine and (R)-aminocarnitine inner salts give beta-hydroxy-gamma-butyrolactone and beta-amino-gamma-butyrolactone respectively (82% and 77%) with the same configuration as the starting material. (R)-Acetylaminocarnitine inner salt gives (R)-beta-acetylamino-gamma-butyrolactone (90%), while (R)-acetylcarnitine gives 2(5H)-furanone under the same reaction conditions (77%, via cyclization and subsequent elimination reaction). (R)-N-Benzyloxycarnitineamide gives a mixture of pyrrolidinone (11%) and furanoyl imidate (50%) derivatives. The direct transformation of waste (S)-carnitine into the valuable (S)-beta-hydroxy-gamma-butyrolactone or (after acetylation) into the precious 2(5H)-furanone is of particular interest.
