Selective displacement of aryl fluorides with hydroquinone: synthesis of 4-phenoxyphenols
摘要:
The selective displacement of a variety of aryl fluorides with hydroquinone has been achieved to give substituted 4-phenoxyphenols 3. In some cases the addition of 18-crown-6 resulted in a significant rate enhancement, and the reactions could be carried out at lower temperature. One of these derivatives, 3a (X = Cl) was converted to 2-propyl-4-(4-chlorophenoxy)phenol 2a, a precursor to the PPAR gamma receptor agonist 1. (c) 2005 Elsevier Ltd. All rights reserved.

A series of 5-aryl thiazolidine-2,4-diones containing 4-phenoxyphenyl side chains was designed, synthesized, and evaluated for PPAR agonist activities. One such compound 28 exhibited comparable levels of glucose correction to rosiglitazone in the db/db mouse type 2 diabetes animal model.

Phenoxyphenyl and phenoxybenzyl oxazolidine-2,4-diones and thiazolidine-2,4-diones of formula (I) are agonists or partial agonists of PPAR gamma and are useful in the treatment and control of hyperglycemia that is symptomatic of type II diabetes, as well as dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, and obesity that are often associated with type 2 diabetes.
Substituted 5-aryl-2,4-thiazolidinediones are potent agonists of PPAR, and are therefore useful in the treatment, control or prevention of diabetes, hyperglycemia, hyperlipidemia (including hypercholesterolemia and hypertriglyceridemia), atherosclerosis, obesity, vascular restenosis, and other PPAR .alpha., .delta. and/or .gamma. mediated diseases, disorders and conditions.
The instant invention is concerned with aryl and heteroaryl oxyacetic acid type compounds which are useful antidiabetic compounds. Compositions and methods for the use of the compounds in the treatment of diabetes and related diseases and for lowering triglyceride levels are also disclosed.

A class of benzopyrancarboxylic acid derivatives comprises compounds that are potent agonists of PPAR alpha and/or gamma, and are therefore useful in the treatment, control or prevention of non-insulin dependent diabetes mellitus (NIDDM), hyperglycemia, dyslipidemia, hyperlipidemia, hypercholesterolemia, hypertriglyceridemia, atherosclerosis, obesity, vascular restenosis, inflammation, and other PPAR alpha and/or gamma mediated diseases, disorders and conditions.
