Via catalysis by a chiral iridium Ir-SpiroPAP catalyst, a range of racemic α-aryl-β-ethoxycarbonyl cyclopentanones were hydrogenated to the corresponding ester-functionalized chiral 2-arylcyclopentanols with three contiguous stereocenters in high yields with excellent

  • Synthesis and 29-14C-labeling of 3α,7α,12α-trihydroxy-27-carboxymethyl-5β-cholestan-26-oic acid. A bile acid occurring in peroxisomal diseases

    日期:1993.8
    The synthesis and C-14-labeling of 3alpha, 7alpha, 12alpha-trihydroxy-27-carboxymethyl-5beta-cholestan-26-oic acid by two different approaches is described. One of them involves chain elongation of cholic acid via Wittig-Horner condensation of its formylated 24-aldehyde with tetraethyl phosphonoglutarate. The resulting cholestenoate, on deprotection and hydrogenation, affords the unusual C29 bile acid in good yield. An alternative procedure consists in a malonic ester synthesis starting from the formylated 24-alcohol which, after conversion into a mesylate, is reacted with sodium salt of 2-carboethoxy-gamma-butyrolactone. Alkaline hydrolysis, decarboxylation, esterification with diazomethane and selective tosylation of the newly introduced primary hydroxyl function give a C28 precursor, which is easily chain-elongated into a labeled or unlabeled C29 bile acid by reaction with cyanide and hydrolysis. Due to the easy lactonization of some of the C28 intermediates, the latter method provides a better way for introducing a C-29 label than the sequence usually employed for carboxyl labeling of bile acids and consisting in a decarboxylative halogenation of the parent acid followed by substitution of the norhalogenide with [C-14]cyanide and hydrolysis. The structure of the synthesized acid or its dimethyl ester is confirmed by C-14 nuclear magnetic resonance spectroscopy and mass spectrometry, and is also shown by gas liquid chromatography to be identical with an authentic sample of biosynthetic C29 dioic bile acid extracted from body fluids of Zellweger patients.
