Add time:08/29/2019    Source:sciencedirect.com

Optically active α-amino acid was asymmetrically synthesized under soluble polymer-supported quinine by homogeneous phase catalytic reaction. The precursor of l-phenylalanine, Ph2NCH(CH2Ph)CO2C2H5 (C24H23NO2, Mr=364.38) has been determined by X-ray diffraction analysis. The crystal belongs to monoclinic system with space group P21/c, a=10.4539(10), b=9.8315(10), c=19.8896(19) Å, α=90.00, β=93.661(2), γ=90.00°, V=2040.0(3) Å3,Z=4, Dc=1.164 mg mm−3, μ=0.074 mm−1, F(000)=760. The final R and wR factors are 0.0463 and 0.1239, respectively, with 3610 (Rint=0.0291) independent reflections.
