YieldReaction ConditionsOperation in experiment
Preparation Example 267 To a suspension of (methoxymethyl)(triphenyl)phosphonium chloride (164.57 g) which had been cooled in a dry ice-acetone bath in THF (500 ml) was added dropwise a solution of n-butyllithium in hexane (concentration 1.65 M, 281.3 ml) at -55C or lower under a nitrogen air flow. Then, the mixed reaction liquid was warmed, followed by stirring at room temperature for 1 hour. After stirring, the mixed reaction liquid was cooled under ice, and a solution of <strong>[17429-02-6]4-hydroxy-4-methylcyclohexanone</strong> (20.51 g) in THF (205 ml) was added dropwise thereto. After dropwise addition, the mixed reaction liquid was warmed to room temperature, followed by stirring for 15 hours. To the mixed reaction liquid were sequentially added water and EtOAc, followed by stirring, and then the organic layer was collected by separation. The aqueous layer was further extracted with EtOAc, and the organic layer was combined, washed with saturated brine, and dried over anhydrous sodium sulfate. After the desiccant was removed, the solvent was evaporated under reduced pressure. The residue was purified by silica gel flash column chromatography (hexane-EtOAc) to obtain 4-(methoxymethylene)-1-methylcyclohexanol (21.37 g).

With selenium(IV) oxide; potassium tert-butylate; In hexane; EXAMPLE 3 This Example illustrates an alternative synthesis of (E)-methyl 3-methoxy-2-[2-(3-methylphenoxy)phenyl]propenoate. A mixture of methyl ortho-bromophenylacetate (4.10 g, prepared as described in Example 1) and selenium dioxide (4.92 g) was stirred for 25 hours at 190 C. After cooling, the mixture was diluted with dichloromethane (100 ml) then filtered through `Supercel`. The filtrate was washed successively with saturated aqueous sodium bicarbonate (*2) and brine, then dried and concentrated to give a yellow liquid (3.60 g) containing (52% by GC-MS) <strong>[122394-38-1]methyl (2-bromobenzoyl)formate</strong> and unreacted methyl ortho-bromophenylacetate. Potassium tert-butoxide (2.33 g) was added to a vigorously-stirred suspension of (methoxymethyl)triphenylphosphonium chloride (7.90 g) in ether (80 ml) at room temperature. After 15 minutes, a solution of the crude <strong>[122394-38-1]methyl (2-bromobenzoyl)formate</strong> (3.60 g) in ether (10 ml) was added in a single portion. After a further 15 minutes, the reaction mixture was poured into water (150 ml), the aqueous and organic layers were separated, and the former was extracted with a further portion of ether (100 ml). The combined ether layers were washed successively with water (*2) and brine, then dried and concentrated to give a yellow oil (5.81 g) containing, in a ratio of about 6:5, the (E)- and (Z)-isomers respectively of methyl 2-(2-bromophenyl)-3-methoxypropenoate. Chromatography using ether:hexane (1:1) as eluant allowed the pure (Z)-isomer (0.450 g) to be isolated as a pale yellow oil, IR (film) 1712, 1638 cm-1, 1 H n.m.r delta 3.71 (3H, s), 3.95 (3H, s), 6.57 (1H, s) p.p.m.
