Phosphoric acid methyl ester

Imidazolides of adenylic acid (ImpA) or uridylic acid (ImpU) are polycondensed to oligonucleotides by means of Zn2+ ions. 1673 The resulting phosphordiester bond was found to be of the 2, 5 type. In the reaction of nucleoside 5 -phosphoric acid methyl ester with ImpA in the presence of MgC, 2, 5 -dinucleotides are formed six to nine times more frequently than the corresponding 3, 5 compounds. 63 Polycondensations of ImpA in aqueous solution in the presence of various divalent metal ions lead to short oligo-adenylic acids (pA) (n = 1—5) mainly with 2, 5 -intemucleotide linkages. With Pb2+, for example, the total yield of oligomers was as high as 57%. 1683 1693... [Pg.275]

To a 12 L 3-neck round bottom flask with stir bar was added 2S-(1-tetrahydro-pyrimid-2-onyl)-3-methyl butanoic acid methyl ester (126 g, 0.588 mol), water (1.3 L), and THF (3.9 L). The solution was cooled to 0°C in an ice-water bath and lithium hydroxide monohydrate (74 g, 1.76 mol) was added in one portion with rapid stirring. The solution was allowed to stir at 0°C for 14 hours. It was then acidified to pH 11 by slow addition of 50% aq. phosphoric acid and the THF was removed in vacuo. The aqueous phase was washed with isopropyl acetate (2 L) and was subsequently acidified to pH by slow addition of 35% aq. HCI. The aqueous layer was then extracted with ethyl acetate. The combined organic layers were concentrated to give the desired product (105 g) as a white solid. The compound was then purified by... [Pg.2075]

This compound with hydriodic acid in acetic acid in the presence of red phosphorous at reflux yielded 5,7-dihydroxy-4-methyl-3H-isobenzofuran-l-one. Condensation of 6-bromo-4-methylhex-4-enoic acid methyl ester and 5,7-dihydroxy-4-methyl-3H-isobenzofuran-l-one with silver oxide in dioxane at room temperature yielded 6-(4,6-dihydroxy-7-methyl-3-oxo-l,3-dihydro-isobenzofuran-5-yl)-4-methylhex-4-enoic acid methyl ester (36% yield).

Beckman rearrangement of the oxime of 7-ketodehydroabietate with phosphoric acid gives the expected lactam (50) and a decarbonylated amine (51). The dihalocarbene adduct of methyl abietate is formed " across the 7(8) double bond. The photo-oxidation of methyl isopimarate, which has a A -double bond, gives 7a-hydroxysandaracopimaric acid methyl ester. However, in the pimaric acid series both the 7a- and 14a-allylic alcohols are formed. [Pg.137]

Compounds which dissolve in concentrated sulphuric acid may be further subdivided into those which are soluble in syrupy phosphoric acid (A) and those which are insoluble in this solvent (B) in general, dissolution takes place without the production of appreciable heat or colour. Those in class A include alcohols, esters, aldehydes, methyl ketones and cyclic ketones provided that they contain less than nine carbon atoms. The solubility limit is somewhat lower than this for ethers thus re-propyl ether dissolves in 85 per cent, phosphoric acid but re-butyl ether and anisole do not. Ethyl benzoate and ethyl malonate are insoluble. [Pg.1050]

Alcohols, esters (but not ethyl benzoate, ethyl malonate or ethyl oxalate), aldehydes, methyl ketones and cyclic ketones containing less than nine carbon atoms as well as ethers containing less than seven carbon atoms are soluble in 85 p>er cent, phosphoric acid. [Pg.1053]
