Sodium borohydride–iodine mediated reduction of γ-lactam carboxylic acids followed by DDQ mediated oxidative aromatisation: a simple approach towards N-aryl-formylpyrroles and 1,3-diaryl-formylpyrroles
摘要:
A simple methodology for the conversion of substituted N-aryl-gamma-lactam 2/3-carboxylic acids to substituted N-aryl-2/3-formyl-pyrroles has been developed. Several N-aryl-gamma-lactam 2/3-carboxylic acids were reduced to substituted (N-aryl-pyrroliden-2/3-yl)-methanols in good yields by using the NaBH4-I-2 system. Aromatisation and in situ oxidation of these alcohols using DDQ produced N-aryl-2/3-formyl-pyrroles, which act as key starting material and intermediates in the synthesis of several bioactive compounds.

This invention provides novel compounds and the novel compounds for use as a medicine, more in particular for the prevention or treatment of neurodegenerative disorders, more specifically certain neurological disorders, such as disorders collectively known as tauopathies, and disorders characterised by cytotoxic α-synuclein amyloidogenesis. The present invention also relates to the use of said novel compounds for the manufacture of medicaments useful for treating such neurodegenerative disorders. The present invention further relates to pharmaceutical compositions including said novel compounds and to methods for the preparation of said novel compounds.

A simple methodology for the conversion of substituted N-aryl-gamma-lactam 2/3-carboxylic acids to substituted N-aryl-2/3-formyl-pyrroles has been developed. Several N-aryl-gamma-lactam 2/3-carboxylic acids were reduced to substituted (N-arylpyri-olidine-2/3-yl)-methanols in good yields at room temperature using sodium borohydride-iodine. Controlled oxidation and aromatisation of these alcohols using DDQ produced N-aryl-2/3-formyl-pyrroles. (C) 2004 Elsevier Ltd. All rights reserved.
