A highly efficient and enantioselective hydrogenation of unprotected β-enamine esters catalyzed by Ir-(S,S)-f-Binaphane complex has been developed. This methodol. provides straightforward access to free β-amino acids in high yields with excellent enantioselectivities up to 97% ee and high reactivities (TON > 5000). This study involved multiple reactions and reactants, such as Methyl (S)-3-amino-3-(4-fluorophenyl)propanoate hydrochloride (cas: 1246174-74-2Category: esters-buliding-blocks).
Methyl (S)-3-amino-3-(4-fluorophenyl)propanoate hydrochloride (cas: 1246174-74-2) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Category: esters-buliding-blocks
