METHOD OF PRODUCING OPTICALLY ACTIVE ALCOHOL

This invention relates to a process for producing optically active alcohols using asymmetric reduction of aromatic ketones. This process gives optically active alcohols in high enantioselectivity at large scale production. Aromatic ketones represented by formula (I) [wherein, R1 are selected from hydrogen atom, halogen atom, lower alkyl group etc. R2 is -(CH2)n-R3 [wherein, n is 1 to 5 integer. R3 are selected from hydrogen atom, halogen atom, lower alkoxycarbonyl group etc. and formula (II) and (III). {wherein, R4 is selected from lower alkyl group (1 to 5 carbon atom) etc. R5 and R6 are the same or different and are selected from hydrogen atom, halogen atom, lower alkyl group etc.}]] are reduced by sodium borohydride, chlorotrimethylsilane and optically active 2-[bis(4-methoxyphenyl)hydroxymethyl]pyrrolidine represented by formula (IV) to give optically active alcohol represented by formula (V) stereoselectively. (wherein, R1 and R2 are as defined above.)

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C20H20FNO4, you can also check out more blogs about189028-95-3

Polymerization of alpha-amino acid N-carboxyanhydrides catalyzed by rare earth tris(borohydride) complexes: Mechanism and hydroxy-endcapped polypeptides

In this work, rare earth tris(borohydride) complexes, Ln(BH 4)3(THF)3 (Ln = Sc, Y, La, and Dy), have been used to catalyze the ring-opening polymerization of gamma-benzyl-L-glutamate N-carboxyanhydride (BLG NCA). All the catalysts show high activities and the resulting poly(gamma-benzyl-L-glutamate)s (PBLGs) are recovered with high yields (?90%). The molecular weights (MWs) of PBLG can be controlled by the molar ratios of monomer to catalyst, and the MW distributions (MWDs) are relatively narrow (as low as 1.16) depending on the rare earth metals and reaction temperatures. Block copolypeptides can be easily synthesized by the sequential addition of two monomers. The obtained P(gamma-benzyl-L-glutamate- b-mu-carbobenzoxy-L-lysine) [P(BLG-b-BLL)] and P(gamma-benzyl-L-glutamate-b- alanine) [P(BLG-b-ALA)] have been well characterized by NMR, gel permeation chromatography, and differential scanning calorimetry measurements. A random copolymer P(BLG-co-BLL) with a narrow MWD of 1.07 has also been synthesized. The polymerization mechanisms have been investigated in detail. The results show that both nucleophilic attack at the 5-CO of NCA and deprotonation of 3-NH of NCA in the initiation process take place simultaneously, resulting in two active centers, that is, an yttrium ALA carbamate derivative [H2BOCH 2(CH)NHC(O)OLni£] and a N-yttriumlated ALA NCA. Propagation then proceeds on these centers via both normal monomer insertion and polycondensation. After termination, two kinds of telechelic polypeptide chains, that is, alpha-hydroxyl-omega-aminotelechelic chains and alpha-carboxylic-omega-aminotelechelic ones, are formed as characterized by MALDI-TOF MS, 1H NMR, 13C NMR, 1H-1H COSY, and 1H-13C HMQC measurements. By decreasing the reaction temperature, the normal monomer insertion pathway can be exclusively selected, forming an unprecedented alpha-hydroxyl-omega-aminotelechelic polypeptide.
