Initially the process utilized butyl acetate as a solvent, but more recently isopropyl ether has been used, although the latter has a much lower partition coefficient for phenol. The reason for this choice of solvent is that the separation of solvent and phenol by distillation is easier and less costly. [Pg.437]

The solvents most commonly employed are water, ethyl and methyl alcohol, ether, benzene, petroleum ether, acetone, glacial acetic acid also two or three solvents may be mixed to get the desired effect as described later. If you still cannot dissolve the compound, try some of these chloroform, carbon disulfide, carbon tetrachloride, ethyl acetate, pyridine, hydrochloric acid, sulfuric acid (acids are usually diluted first), nitrobenzene, aniline, phenol, dioxan, ethylene dichloride, di, tri, tetrachloroethylene, tetrachloroethane, dichloroethyl ether, cyclohexane, cyclohexanol, tetralin, decalin, triacetin, ethylene glycol and its esters and ethers, butyl alcohol, diacetone alcohol, ethyl lactate, isopropyl ether, etc. [Pg.10]

Following the successful demonstration of an enamine photocyclization, Ninomiya synthesized ( )-cryptaustoline iodide from 44b. Irradiation of isopropyl ether 44b gave a mixture of dibenzopyrrocolines 45b and 45c in 12 and 11% yield, respectively. The isopropyl ether group in 45c was selectively hydrolyzed by hydrobromic acid, and the resulting phenolic compound was converted to cryptaustoline iodide with methyl iodide. An attempt to photocyclize an O-benzyl ether analog of 44b was less satisfactory. [Pg.114]

Methylation of alkaloids containing either phenolic hydroxy groups or secondary amine functions is the most common procedure for converting such alkaloids to known derivatives many examples are given in Section II,C. Diazomethane is the reagent of choice for O-methylation, and diazoethane for O-ethylation. It is possible to effect O-alkylation in the presence of secondary amine functions, as in the conversion of peinamine to its trideuteriomethyl ether (Section II,C,92) and of A-desmethylthalrugosidine to the O-ethyl ether (Section II,C,29). Another O-alkylation method, exemplified by the preparation of O-methyl, O-ethyl, and O-isopropyl ethers of berbamine (364), consisted of heating the alkaloid in... [Pg.104]

Protection of phenols. Aryl isopropyl ethers are also obtained by reaction of phenols with 2-bromopropane in DMF. The protective group is cleaved by BCl, in C HjCIj at 0°, but it is stable to SnCl, or TiCl, under these conditions. It is recommended for protection of phenolic groups during formylation with ilichloromethyl methyl ether in the presence of SnCl,. [Pg.341]
