Dimethyl-2-oxybutyl 4-Methoxyphenyl Tellurium Dichloridch A suspension of 1.02 g (3.0 mmol) of 4-methoxyphenyl tellurium trichloride in 10 m/ benzene kept under an atmosphere of nitrogen is mixed with 0.3 g (3.0 mmol) iert.-butyl methyl ketone. The mixture is refluxed for 72 h and then treated with methanol/watcr (1 1) and extracted with chloroform. The organic layer is separated, dried with anhydrous magnesium sulfate, filtered, and the solvent evaporated from the filtrate. The residual yellow oil is chromatographed on a silica gel column with chloroform as the mobile phase. The product is rccrystallized from chloroform/petroleum ether (30-60°) yield 60%, m.p. 90-92°. 

An effort was made to prepare a butyl analogue containing a ring, but it was never completed. This was the cyclopropylmethyl isomer, 2,5-dimethoxy-4-cyclo-propylmethylamphetamine hydrochloride, DOCPM. Only the first step of its synthesis was complete (the reaction of cyclopropylcarboxylic acid chloride with p-dimethoxybenzene) and even it went badly. The desired ketone (2,5-dimethoxyphenyl cyclopropyl ketone) was most difficult to separate from the recovered starting ether. A promising approach would be the isolation of the phenol (2-hydroxy-5-methoxyphenyl cyclopropyl ketone) which is a beautiful yellow solid with a melting point of 99-100 °C from methanol. Anal. (Cl 1 HI203) C,H. It then could be methylated to the wanted intermediate. It is the major product when the reaction is conducted with anhydrous aluminum chloride in methylene chloride.

AgF as catalysts in a 1 20 mixture of methanol and dichloromethane at low temperatures (Scheme 18.24). Table 18.3 shows examples of the protonation of silyl enolates (71) leading to the corresponding nonracemic ketones (72). Moderate asymmetric induction is observed with the silyl enolates of 2-methyl-l-tetralone and its 2-ethyl derivative (entries 1 and 2). Employment of 2,2,6-trimethylcyclohexanone-derived silyl enolate results in unexpectedly high enantioselectivity of more than 85% ee (entry 3). 2-Arylcycloalkanones are undoubtedly suitable substrates for the protonation and in fact, quite high enantiomeric excesses are obtained for the silyl enolates of 2-phenylcyclohexanone and 2-phenylcycloheptanone (entries 4-6). As for the substrates bearing a p-methoxyphenyl or 2-naphthyl group, almost perfect enantioface control has been achieved (entries 7 and 8). 

D) 4 -[N-Ethyi-1 "-Methyl-2 -(4" -Methoxyphenyl)Ethylamino]Butyi-3,4-Dimethoxybenzoate Hydrochloride 10.3 g of 4 -iodobutyl-3,4-dimethoxybenzoate and 11.0 g of N-ethyl-p-methoxyphenylisopropylamine (obtained by catalytic reduction of an alcoholic solution of an excess quantity (60%) of p-methoxy-phenyl-acetone, to which was added a 33% (weight-for-weight) aqueous solution of ethylamine, with Pt as a catalyst), were boiled in 200 ml of methyl ethyl ketone for 20 hours, cooled and the iodine ion was determined the reaction was found to be complete. Then the methyl ethyl ketone was evaporated in vacuo and the residue was dissolved in 300 ml of water and 30 ml of ether the layers were separated and the water layer was extracted twice more with 20 ml portions of ether. 

Methoxyphenyl 2-Oxo-2-phenylethyl Tellurium Dichloride1 0.34 g (1 mmol) of 4-mcthoxyphenyl tellurium trichloride and 0.36 g (3 mmol) of methyl phenyl ketone are intimately mixed and allowed to stand for 48 h. During this time the product crystallizes. Diethyl ether is added to the mixture which is then shaken thoroughly. The ether is decanted, the crystals are quickly washed with a small amount of cold methanol, and recrystallized from benzene/petroleum ether (b.p. 50-70°) yield 0.25 g (60%) m.p. 137".
