Safety of (S)-Methyl 3-hydroxybutanoate. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: (S)-Methyl 3-hydroxybutanoate, is researched, Molecular C5H10O3, CAS is 53562-86-0, about Rhizopus arrhizus mediated asymmetric reduction of alkyl 3-oxobutanoates. Author is Salvi, Neeta A.; Chattopadhyay, Subrata.
Alkyl 3-oxobutanoates MeCOCH2CO2R (R = Me, Et, H2C:CHCH2, Me2CHCH2, Me3C) were reduced enantioselectively to the corresponding (S)-alcs. MeCH(OH)CH2CO2R by the fungus Rhizopus arrhizus and other Rhizopus sp. The best result obtained was with t-Bu 3-oxobutanoate, which was reduced by R. arrhizus with 99% enantiomeric excess and in 68% isolated yield.
