Reference of 4254-15-3, New research progress on 4254-15-3 in 2021. Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. 4254-15-3, Name is (S)-Propane-1,2-diol, molecular formula is C3H8O2. In a article，once mentioned of 4254-15-3
A series of new C2-symmetric chiral aza crown ether macrocycles 1-4 have been synthesized from (S)-3-aryloxy-1,2-propanediol and (S)-1,2-propanediol for the enantiomeric recognition of amino acid ester derivatives. These new macrocycles have been shown to be strong complexing agents for primary organic ammonium salts (with K up to 176.93 M-1 and DeltaG up to 12.81 kJ mol-1) by 1H NMR titration. These macrocyclic host exhibited enantioselective bonding toward the d-enantiomer of phenylalanine methyl ester hydrochloride with KD/KL up to 6.87 in CDCl3 with 0.25% CD3OD.
