    摘要:
    为了确定肾上腺素(Epi)在中枢神经系统中的功能,我们针对了催化Epi的生物合成最后一步的酶,即苯乙醇胺N-甲基转移酶(PNMT; EC 2.1.1.28)。1,2,3,4-四氢异喹啉(THIQs)是该酶的抑制剂,但对α2-肾上腺素受体也表现出亲和力。为了进一步了解THIQs在PNMT活性位点上的结合方式,并试图进一步提高THIQ型抑制剂相对于α2-肾上腺素受体的选择性,一系列顺式和反式1,3-二甲基-7取代-THIQ合成。对这些化合物的评估表明,基于7位取代基的亲脂性,THIQs在PNMT活性位点以两种不同的方向结合。然而,

  • Super Acid-Induced Pummerer-Type Cyclization Reaction: Improvement in the Synthesis of Chiral 1,3-Dimethyl-1,2,3,4-tetrahydroisoquinolines

    Improved synthesis of four stereoisomeric chiral 1,3-dimethyl-1,2,3,4-tetrahydroisoquinolines (1a, b, ent-1a, b) was achieved via the super acid-induced cyclization of chiral N-[1-methyl-2-(phenylsulfinyl)ethyl]-N-(1-phenylethyl)formamides (4a, b, ent-4a, b) using the Pummerer-type cyclization reaction as a key step. The cyclization leading to the isoquinoline ring proceeded in a quantitative manner

  • Conformational Analysis. 50. <i>C</i>-Methyl-1,2,3,4-tetrahydroisoquinolines
    作者:Edward M. Olefirowicz、Ernest L. Eliel
    DOI:10.1021/jo971257r
    日期:1997.12.1
    Conformational equilibria in 1-, 3-, and 4-methyl-1,2,3,4-tetrahydroisoquinolines (THIQs) and the diastereomeric pairs of their 1,3- and 1,4-dimethyl homologs have been determined by measurement of H-3/H-4(trans) coupling constants and have been confirmed by molecular mechanics [MMP2(85]) calculations. The experimental -Delta G degrees values (a --> e) for the monomethyl compounds (computed values in parentheses) in kcal mol(-1) are Me-1, 0.56 (0.46); Me-3, 1.63 (1.53); and Me-4, -0.32 (-0.22). Agreement of experimental and calculated values is very goad as is the additivity of values for the dimethyl compounds (Table 1). Values for the corresponding hydrochlorides are Me-1, 0.19 (-0.34); Me-3, 1.15 (1.46); and Me-4, 0.35 (0.10) kcal mol(-1). The less than satisfactory agreement of experimental with computed data here is probably due to neglect of solvation. The very small or negative Delta G degrees values for Me-1 and Me-4 were ascribed not only to the pseudoaxial (rather than axial) nature of Me(ax) and the absence of a syn-axial hydrogen on the side of the benzene ring but also to a peri interaction with H(8) and H(5), respectively, destabilizing equatorial methyl at positions 1 and 4. This was confirmed by comparing computed conformational energy values with values at corresponding positions in Delta(3,4)-tetrahydropyridines (THPs). While Delta G degrees in the two series is the same for Me-3 (THIQ numbering), that for Me-1 and Me-4 is considerably smaller in the THIQ than in the THP series which latter is devoid of peri hydrogens.
