Sodium hydnde

A-Fluoro-2,4,6-tnmethylpyndmium inflate (1 mmol) is added m several portions at room temperature to a tetrahydrofuran solution of sodium diethyl phenyl-malonate, obtained from 1 mmol of diethyl phenyl malonate and sodium hydnde at 0 C in tetrahydrofuran The reaction imxture is poured mto dilute hydrochlonc acid and extracted with ether The ether extract is washed with sodium bicarbonate and water and dned over magnesium sulfate The oily residue obtamed after removal of tihe ether is chromatographed on sihca gel (dichloromethane-hexane, 1 1) to give diethyl fluorophenylmalonate in 83% yield... [Pg.166]

Mescaline a hallucinogenic amine obtained from the peyote cactus has been synthesized in two steps from 3 4 5 trimethoxybenzyl bromide The first step is nucleophilic substitution by sodium cyanide The second step is a lithium aluminum hydnde reduction What is the structure of mescaline" ... [Pg.968]

The well-known reduction of carbonyl groups to alcohols has been refined in recent studies to render the reaction more regioselective and more stereoselective Per-fluorodiketones are reduced by lithium aluminum hydride to the corresponding diols, but the use of potassium or sodium borohydride allows isolation of the ketoalcohol Similarly, a perfluoroketo acid fluonde yields diol with lithium aluminum hydnde, but the related hydroxy acid is obtainable with potassium borohydnde [i f] (equations 46 and 47)... [Pg.308]

The Al-dtfluoroaimno substituent with no a-hydrogen is resistant to lithium alununum hydnde [5/] (equation 65), and the selective reduction of the ester functions of polychlorofluorocarboxylates to alcohols without loss of chlorme is accomplished with sodium borohydnde [52] (equation 66)... [Pg.312]
