Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 37443-42-8, is researched, Molecular C6H10O3, about A scalable chemoenzymic preparation of (R)-tetrahydrofuran-2-carboxylic acid, the main research direction is chemoenzymic asym preparation tetrahydrofurancarboxylic acid; protease asym preparation tetrahydrofurancarboxylic acid.COA of Formula: C6H10O3.
To develop a practical scalable approach to (R)-tetrahydrofuran-2-carboxylic acid (I), a chiral building block for furopenem, enantioselective hydrolysis of its esters is explored: When Et (±)-tetrahydrofuran-2-carboxylate (II, 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 I in 94.4% ee. On separation from the leftover antipodal (S)-II by partition, I is treated with dicyclohexylamine in Me Et ketone/methanol (5:1) to precipitate the crystalline salt that contains I of >99% ee in 22% overall yield from II.
After consulting a lot of data, we found that this compound(37443-42-8)COA of Formula: C6H10O3 can be used in many types of reactions. And in most cases, this compound has more advantages.
