Methyl iodide, acetic anhydride, Oxone (potassium peroxymonosulfate), Aliquot 336 (methyl tri-n-octylammonium chloride), sodium tungstate dihydrate and N,N-dimethylaminopyridine (DMAP) were purchased from Aldrich Chemical Co. and used as received. 3,4-Epoxycyclohexylmethyl 3, 4 -epoxycyclohexane carboxylate (ERL 4221) and 4-vinylcyclohexene dioxide were used as purchased from the Union Carbide Corp. (4-n-Octyloxyphenyl)phenyliodonium hexafluoroantimonate used as a photoinitiator was prepared by a procedure described previously (4). [Pg.83]

Into a 100 mL round bottom flask fitted with a magnetic stirrer, and a condenser were placed 10.09 g (0.08 mol) of 3-cyclohexene-1-carboxylic acid, 12.81 g (0.40 mol) of methanol and 1.56 g (0.016 mol) of concentrated sulfuric acid. The reaction mixture was heated under reflux for 5 hr in an oil bath. After this time, the reaction mixture was diluted with water and then extracted several times with ether. The organic phase was neutralized by washing with a dilute solution of sodium carbonate, then with distilled water and finally dried over anhydrous magnesium sulfate. After filtration,... [Pg.83]

The key intermediate, 3-methyl-5-oxo-3-cyclohexene-1-carboxylic acid(V), was resolved as the (-)-quinine salt. A new approach to determining the optical purity of carboxylic acids is discussed. [Pg.87]

Juvabione, the compound responsible for this activity, was isolated from the balsam fir, Abies balsamea (L.) Miller, and identified as the methyl ester of todomatuic acid, (+)-4(i )-[ 1 R)-S -dimethyl-3 -oxohexyl]-1-cyclohexene-1-carboxylic acid [87]. This compound is a sesquiterpenoid (Fig. (6)) with a cyclohexene group and an a,(3-unsaturated methyl ester group the chemical data for this compound are summarized in Appendix II, Table 1. The IR spectrum suggests that there is a carbonyl ester group present in conjunction with a double bond (1722 and 1645 cm 1) and also an isolated carbonyl group (1712 cm 1) [87].

The reaction of 3-cyclohexene-1-carboxylic acid with ECH (molar ratio 1 8) was investigated at 65-85 °C in presence of a catalyst (KCl or tetramethylammo-nium chloride). After 2 h the formation of the chlorohydrin ester was completed with 100% quantitative yield. However, the hydrochlorination results in a low yield of epoxy groups and a low conversion of chlorohydrin to epoxy groups. The alkali partial consumption for hydrolysis of the ester groups, even at room temperature, is another reason. [Pg.70]
