    Novel (S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acids: Peroxisome proliferator-activated receptor γ selective agonists with protein-tyrosine phosphatase 1B inhibition
    摘要:
    A novel series of 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid derivatives were synthesized and (S)-2-[(2E,4E)- hexadienoyl]-7-(2-(5-methyl-2-[( 1E)-5-methylhexen-1-yl]oxazol-4-yl]ethoxy)-1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (14i) was identified as a potent human peroxisome proliferator-activated receptor gamma (PPAR gamma) selective agonist (EC(50) = 0.03 mu M) and human protein-tyrosine phosphatase 1B (PTP-1B) inhibitor (IC(50) = 1.18 mu M). C(max) after oral administration of 14i at 10 mg/kg was 2.2 mu g/ml (4.5 mu M) in male SD rats. Repeated administration of 14i and rosiglitazone for 14 days dose-dependently decreased plasma glucose levels, ED(50) = 4.3 and 23 mg/kg/day, respectively, in male KK-A(y) mice. In female SD rats, repeated administration of 14i at 12.5-100 mg/kg/day for 28 days had no effect on the hematocrit value (Ht) and red blood cell count (RBC), while rosiglitazone significantly decreased them from 25 mg/kg/day. In conclusion, 14i showed about a fivefold stronger hypoglycemic effect and fourfold or more weaker hemodilution effect than rosiglitazone, indicating that 14i is 20-fold or more safer than rosiglitazone. Compound 14i is a promising candidate for an efficacious and safe anti-diabetic drug targeting PPAR gamma and PTP-1B. (C) 2011 Elsevier Ltd. All rights reserved.

    usually above 95:5. The relative efficiency of a range of acids (trifluoroacetic, difluoroacetic, acetic, triflic) is assessed showing TFA and TfOH as the most efficient and acetic acid as a totally inefficient reaction promoter. The new procedure complements the Lewis acid promoted reaction previously described by our group in two aspects: First, stereodivergent results are obtained for the Lewis acid
    证明了单独使用布朗斯台德酸有效促进 N-烯酰基恶唑烷-2-硫酮中的硫转移过程以产生 β-巯基羰基衍生物的能力。该反应对一系列烷基取代的 N-烯酰基恶唑烷-2-硫酮(dr 通常高于 98:2)进行了基本上完美的非对映控制,并且对大多数芳基取代的对应物(dr 通常高于 92:8)具有高选择性。重要的是,该反应在 β,β-二取代的 N-烯酰基恶唑烷-2-硫酮中也非常有效,产生选择性通常高于 95:5 的四元 CS 立体中心。评估了一系列酸(三氟乙酸、二氟乙酸、乙酸、三氟甲磺酸)的相对效率,显示 TFA 和 TfOH 是最有效的,而乙酸则是完全低效的反应促进剂。新程序在两个方面补充了我们小组先前描述的路易斯酸促进反应:首先,对路易斯酸或布朗斯台德酸促进的β,β-二取代烯酰基化合物的反应获得了立体发散结果。其次,虽然布朗斯台德酸促进的反应是立体有择的,在底物 E/Z 构型和产物立体化学之间提供了良好的相关性,但由路易斯酸

    [reaction: see text] A general strategy for highly enantioselective 1,3-dipolar cycloaddition of diazoesters to beta-substituted, alpha-substituted, and alpha,beta-disubstituted alpha,beta-unsaturated pyrazolidinone imides is described. Cycloadditions utilizing less reactive alpha,beta-disubstituted dipolarophiles require elevated reaction temperatures, but still provide the corresponding pyrazolines

    In the presence of diethylzinc as a stoichiometric reductant, Ni(acac) 2 functions as an efficient precatalyst for the reductive aldol cyclization of alpha,beta-unsaturated carbonyl compounds tethered to a ketone electrophile through an amide or an ester linkage. The reactions are tolerant of a wide range of substitution at both alpha,beta-unsaturated carbonyl and ketone components and proceed smoothly

This strategy gives a variety of functionalized thioethers in moderate to excellent yields in a simple and efficient way. Importantly, the substrate scope is not limited to aromatic amides; diverse alkenyl amides are also compatible. Furthermore, this synthetic approach provides a potentially feasible
