  Substituted 2-aminothiazoles are exceptional inhibitors of neuronal degeneration in tau-driven models of Alzheimer’s disease

  摘要：

  A novel series of 2-aminothiazoles with strong protection in an Alzheimer's disease (AD) model comprising tau-induced neuronal toxicity is disclosed. These derivatives can be synthesized in one-pot and a small SAR of the substitution within these series afforded several compounds that counteracted tau-induced cell toxicity at nanomolar concentrations. These congeners therefore have strong potential as possible treatment for Alzheimer's disease and other related tauopathies. (C) 2011 Elsevier B.V. All rights reserved.

• Microwave-Assisted Domino Reactions of Propargylamines with Isothiocyanates: Selective Synthesis of 2-Aminothiazoles and 2-Amino-4-methylenethiazolines

  versatile microwave-assisted protocol for the synthesis of 2-aminothiazoles has been developed. The domino reaction of propargylamines and isothiocyanates in the presence of catalytic PTSA leads to the selective synthesis of 2-aminothiazoles at temperatures above 130 °C and in a few minutes. The same reaction carried out at lower temperatures leads to the formation of the tautomeric 2-amino-4-methylenethiazolines

  functional ligand [(p-cymene)Ru(2,2′-bpyO)(H2O)] was found to be a general and efficient catalyst for the direct N-alkylation of 2-amino-azoles with alcohols to 2-(N-alkylamino)zoles. In the presence of catalyst (0.5 mol %), a range of desirable products were obtained with complete regioselectivity. Mechanistic experiments supported that functional groups in bpy ligand are crucially important for the catalytic

  A simple and efficient method has been developed for the synthesis of 2-aminothiazoles and N-allylthioureas from commercially available materials in one pot by using a supported reagents system, KSCN/SiO2-RNH3OAc/Al2O3, in which alpha-halo ketone reacts first KSCN/SiO2 and the product, alpha.-thiocyanatoketone, reacts with RNH3OAc/Al2O3 to give the final product, 2-aminothiazoles, in good yield and allyl bromide reacts with KSCN/SiO2 and the product, allyl isothiocyanate, reacts with RNH3OAc/Al2O3 to give N-allylthiourea.
