Ethyl 4-toluate

Ethyl toluates, e204, e205, e206 Ethyl p-tolyl ether, m3 7 3 Ethyl trimethylacetate, el28 Ethyl vanillin, e46 Ethyne, a41 Ethynylbenzene, p84... [Pg.227]

V-Methyl-2-methyl-3-(benzotriazol-l-yl)propanamide (631), on treatment with two equivalents of butyllithium, forms a dianion that reacts with alkyl and benzyl halides, aldehydes, and ketones to give monosubstituted products (632) (Scheme 124). With ethyl / -toluate, however, a lactam (634) is formed. The alkylated derivatives (632) eliminate benzotriazole upon treatment with NaOEt to afford trisubstituted a,)8-unsaturated amides (633) <93JHC1261>. [Pg.94]

The catalyst is inactive for the hydrogenation of the (isolated) benzene nucleus and so may bo used for the hydrogenation of aromatic compounds containing aldehyde, keto, carbalkoxy or amide groups to the corresponding alcohols, amines, etc., e.g., ethyl benzoate to benzyl alcohol methyl p-toluate to p-methylbenzyl alcohol ethyl cinnamate to 3 phenyl 1-propanol. [Pg.873]

Reactions of A-acyloxy-A-alkoxyamides (90) with A-methylaniline in methanol or aqueous acetonitrile afforded quantitative yields of esters (130), carboxylic acid (132) and half an equivalent of A,A -dimethyl-A,A -diphenyltetrazene (131) (equation 15). The reaction is promoted by polar solvents and ester formation was shown to involve an intramolecular process a crossover experiment using a mixture of A-acetoxy-iV-butoxy-4-toluamide (90, R = Bu, R = Me, R = 4-MeC6H4) and A-acetoxy-A-ethoxybenzamide (90, R = Et, R = Me, R = Ph) afforded clean yields of butyl 4-toluate (130, R = Bu, R = 4-McC6H4) and ethyl benzoate (130, R = Et, R = Ph)". ... [Pg.883]

In the aromatic series, acetophenone and methyl iodide, for example, yield phenyldimethylcarbinol. An important step in the synthesis of i-terpineol is the preparation of ethyl-S-hydroxy-hexahydro-p-toluate from ethyl-S-ketohexahydrobenzoate and magnesium methyl iodide. [Pg.73]
