A convenient synthesis of piperidine-based b-amino alcohols from l-Phe and highly enantioselective addition of diethyl zinc to aldehydes: A convenient synthesis of piperidine-based b-amino alcohols from l-Phe and highly enantioselective addition of diethyl zinc to aldehydes. Da, Chao-shan; Han, Zhi-jian; Ni, Ming; Yang, Fan; Liu, Da-xue; Zhou, Yi-feng; Wang, Rui (School of Life Sciences, Department of Biochemistry & Molecular Biology, Lanzhou University, Lanzhou 730000, Peop. Rep. China). Tetrahedron: Asymmetry, 14(6), 659-665 (English) 2003 Elsevier Science Ltd. CODEN: TASYE3. ISSN: 0957-4166. DOCUMENT TYPE: Journal CA Section: 25 (Benzene, Its Derivatives, and Condensed Benzenoid Compounds) Section cross-reference(s): 27 b-Amino alcs. were easily prepd. from L-phenylalanine in three simple straightforward steps. The key intermediate compd. (-)-(aS)-a-(phenylmethyl)-1-piperidineacetic acid Me ester was achieved in high yield (up to 92%) with glutaraldehyde and NaBH4/H2SO4 in THF at room temp. Amino alcs. thus prepd. included (bS)-a,a-diphenyl-b-(phenylmethyl)-1-piperidineethanol, (bS)-a,a-dimethyl-b-(phenylmethyl)-1-piperidineethanol, (bS)-a,a-diethyl-b-(phenylmethyl)-1-piperidineethanol (I), and (bS)-a,a-dipropyl-b-(phenylmethyl)-1-piperidineethanol (II), and (-)-1-[(1S)-2-phenyl-1-(1-piperidinyl)ethyl]cyclopentanol. These five ligands were applied to catalyze enantioselective addn. of di-Et zinc to aldehydes, high asym. induction was obsd. with I and II, and the ee value was up to 98%. The effect of the substituents on the nitrogen atom was also obsd. via comparing piperidine-based amino alcs. with pyrrolidine-based similar ligands. (bS)-a,a-Diethyl-b-(phenylmethyl)-1-Pyrrolidineethanol and (bS)-a,a-diphenyl-b-(phenylmethyl)-1-Pyrrolidineethanol were less efficient ligands.

CLASS: IC: C09B067-00. APPLICATION: DE 76-2640602 9 Sep 1976. DOCUMENT TYPE: Patent CA Section: 39 (Textiles) Sulfo group-contg. azo and anthraquinone dyes are converted to powd., easily water-sol. compns. which do not gel when dissolved in H2O by treating an aq. mixt. of the dye with I (R = H, Me; X = CH2, O, NH, C1-4 alkylimino, NCH2CHROH; m, n = 0-4, m + n = 3-4) or II (R = H, Me; R1 = H, C1-4 alkyl) to form the corresponding ammonium salt, dilg. with a nonelectrolyte, and drying. The ammonium forming compds. are N-(2-hydroxyethyl)morpholine [622-40-2], [bis(2-hydroxyethyl)amino]benzene [120-07-0], N-(2-hydroxyethyl)piperidine [3040-44-6], N-(2-hydroxyethyl)pyrrolidine [2955-88-6], and N-(2-hydroxypropyl)pyrrolidine [42122-41-8].
