Sodium borohydride–iodine mediated reduction of γ-lactam carboxylic acids followed by DDQ mediated oxidative aromatisation: a facile entry to N-aryl-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-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.

acquired resistance in clinical trials of c-Met inhibitors, based on the synergistic effects between c-Met and HDAC, novel c-Met and HDAC dual inhibitors were designed and synthesized. We introduced 2-pyrrolidinone to form the 5-atoms linker for c-Met inhibitor and hydroxamic acid as a zinc binding motif for HDAC inhibitor. The highly active dual inhibitor 15f showed excellent and balanced activity against
