Product Details of 58081-05-3. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: (R)-4-Hydroxydihydrofuran-2(3H)-one, is researched, Molecular C4H6O3, CAS is 58081-05-3, about A novel generation of optically active ethyl 4-chloro-3-hydroxybutyrate as a C4 chiral building unit using microbial dechlorination. Author is Suzuki, Toshio; Idogaki, Hideaki; Kasai, Naoya.
A novel procedure for the generation of optically active Et 4-chloro-3-hydroxybutyrate using bacterial cells was developed. Et (S)-4-chloro-3-hydroxybutyrate was prepared by Pseudomonas sp. OS-K-29, which stereoselectively assimilates 2,3-dichloro-1-propanol. The reaction was based on its kinetic dehalogenation for both enantiomers using the resting cells. The obtained 4-chloro-3-hydroxybutyrate had high enantiomeric excess of >98% with a yield of 33% at the microbial resolution step. Moreover, several C4 compounds having the 4-chloro-3-hydroxyl function were also resolved and gave good enantiomeric purities (>95% ee). Et (R)-4-chloro-3-hydroxybutyrate was also obtained with high enantiomeric purity (>98% ee) using the cells of Pseudomonas sp DS-K-NR818.
