New discoveries in chemical research and development in 2021. Formula: C15H19NO4, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 166591-85-1, Name is 2-(tert-Butoxycarbonyl)-1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, molecular formula is C15H19NO4. In a Article，once mentioned of 166591-85-1

To develop a practical scalable approach to (R)-tetrahydrofuran-2-carboxylic acid (THFC) 1, a chiral building block for furopenem 2, enantioselective hydrolysis of its esters is explored: When ethyl (±)-tetrahydrofuran-2-carboxylate 3d (2 M, 288 g/L) is digested by an Aspergillus melleus protease {0.2% (w/v)} in a 1.5 M potassium phosphate buffer (pH 8) for 20 h, enantioselective hydrolysis proceeds with E=60 to give (R)-THFC 1 in 94.4% ee. On separation from the left-over antipodal ester (S)-3d by partition, (R)-THFC 1 is treated with N,N-dicyclohexylamine (DCHA) in methyl ethyl ketone/methanol (5:1) to precipitate the crystalline salt 4 that contains (R)-THFC 1 of >99% ee in 22% overall yield from (±)-3d.

The title heterocycles (3) have been obtained by a two-step synthesis; namely an initial intramolecular sulphonamidomethylation of N-aralkylsulphonamides (1) in acid media followed by desulphonylation of compounds (2) under moderate conditions, either by reduction or acid hydrolysis.Generally both steps gave good or high yields of compounds (3) variously substituted in the aromatic ring and with a six-, seven-, or eight-membered heterocyclic ring.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 82771-60-6, you can also check out more blogs about82771-60-6
