Peracids m-CPBA and CF3CO3H have been used in epoxidations of substrates with two mnable allylic directing groups expected to direct the peracids to opposite faces of the alkene. Control of face selectivity was observed and attributed to the different binding abilities of the two peracids to the various allylic functionalities, carbamate on one side of the alkene and alcohol, methyl ester, acetate, trifluoroacetate, or TBS-ether on the other. The conversion of A-mono-protected and A-di-protected cyclopent-... [Pg.518]

Ketolithocholic acid (10 g) is methylated by dissolving in methanol (200 ml) containing cone. HCl (12 ml). After being kept at room temperature overnight, the mixture is diluted with water and extracted with ether. The semicrystalline residue from the ether extract is subjected to acetylation with acetic anhydride (10 ml) in pyridine (10 ml) at room temperature overnight. The methyl ester acetate (XXXI) crystallizes upon addition of ice water to the reaction mixture, and is recrystallized from acetone and water m.p. 140-142 °C yield, almost quantitative. [Pg.112]

Bromination of the above 7-keto derivative (XXXI) has been described by Takeda et al. (50). In a glass-stoppered bottle, the methyl ester acetate (XXXI, 3 g) is dissolved in acetic acid (50 ml) and an acetic acid solution (10 ml) of bromine (1.08 g) is introduced. Bromination is initiated by addition of HBr (1 ml 30% acetic acid solution). The color of bromine fades in about... [Pg.112]

Column adsorption chromatography should be applied when one deals with very crude extracts, such as those obtained from feces, and when a group separation between mono-, di-, and trisubstituted hydroxycholanoic acids is desirable. It may also be used for large-scale purification of a specific bile acid, e.g., in synthetic work. Silicic acid should be used for free bile acids since more active adsorbents may give incomplete recoveries. Methyl ester or methyl ester acetates are usually best separated on aluminum oxide. In...

For the identification of bile acids in bile from man and different animals, Kuksis (13) and co-workers have used ion-exchange chromatography for the separation of glycine- and taurine-conjugated bile acids. After alkaline hydrolysis, extraction, and methylation, the bile acids were analyzed on SE-30 and QF-1 columns. Tentative identifications were supported by additional gas-liquid chromatographic analysis of methyl ester acetates and methyl ester trifluoroacetates. The latter derivatives were also analyzed on OV-17 columns (117). [Pg.164]
