L-770,644 (9c) is a potent and selective agonist of the human β3 adrenergic receptor (EC50 = 13 nM). It shows good oral bioavailability in both dogs and rats (%F = 27), and is a full agonist for glycerolemia in the rhesus monkey (ED50 = 0.21 mg/kg). Based on its desirable in vitro and in vivo properties, L-770,644 was chosen for further preclinical evaluation.

A chemoenzymatic synthesis of β3 agonist 1 suitable for large scale preparation is described. The key chiral 3-pyridylethanolamine intermediate (R)-7 was prepared via an improved Neber rearrangement and a yeast-mediated asymmetric reduction. The tetrazolone fragment of the molecule was constructed via a dipolar cycloaddition between 1-(cyclopentyl)-3-propylazide and p-chlorosulfonyl phenylisocyanate. Sulfonamide coupling of these two intermediates under Shotten-Baumann conditions, followed by a borane reduction of the amide afforded 1 in 20-32% overall yield from 3-acetylpyridine.
SUBSTITUTED SULFONAMIDES AS SELECTIVE BETA3 AGONISTS FOR THE TREATMENT OF DIABETES AND OBESITY

Substituted sulfonamides are selective β 3 adrenergic receptor agonists with very little β 1 and β 2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent
