The reaction mixture is slowly... 

Method A. Enantiomerically pure ethyl (R-)2-fluorohexanoate (60% hydrolysis). A 1-L Morton flask equipped with a mechanical stirrer, glass baffle, an electrode connected to a pH control unit and an addition tube connected to a syringe pump, is charged with 300 mL of 0.05 M aqueous phosphate buffer (pH 7.0) (Fisher), 300 mL of deionized water, and 70 g (0.43 mol) of ethyl 2-fluorohexanoate. The resulting mixture is stirred for several minutes and the pH is adjusted to 7.0 with the addition of a few... 

C. (+)-(2R,8aS)-10-(Camphorylsulfonyl)oxaziridine. A 5-L, three-necked, round-bottomed Morton flask is equipped with an efficient mechanical stirrer, a 125-mm Teflon stirring blade, a Safe Lab stirring bearing (Note 6), and a 500-mL addition... 

Several types of equipment were used to prepare the latexes. A five gallon glass reactor, five and two liter Morton flasks equipped with condensers, stainless steel stirrers, thermoregulators, and nitrogen inlets were used to prepare the seed latexes... 

Biphasic basic oxidation using technical grade (50-60%) 3-chloroperbenzoic acid affords this oxaziridine in - 4 hr In a 2-L, three-necked, Morton-flask equipped with a mechanical stirrer was placed 22.6 g (0.083 mol) of crude (+)-[(7,7-dimethoxycamphoryl)sulfonyl]imine, 42.6 g (0.13 mol) of 3-chloroperoxybenzoic acid (50-60%) in 450 mL of methylene chloride, and 450 mL of saturated potassium carbonate solution. The reaction mixture was stirred vigorously until the oxidation was complete as indicated by TLC (Note 27) at which time 500 mL of water was added, the organic layer was separated and the aqueous layer was extracted with methylene chloride (2 x 500 mL). The combined organic extracts were washed with saturated sodium sulfite (300 mL) and water (300 mL), and dried over anhydrous magnesium sulfate. 

A. N-(Benzyloxycarbonyl)-L-wethionine methyl ester 2). A 3-L, three-necked, Morton flask equipped with an efficient mechanical stirrer, thermometer, and a dropping funnel is charged with L-methionine methyl ester hydrochloride (117.6 g,... 

An oven-dried, three-necked, 1-L, round-bottomed Morton flask equipped with a mechanical stirrer, gas bubbler outlet, 125-mL, pressure-equalizing addition funnei fitted with a rubber septum, and a nitrogen inlet (Note 1) is charged with 11.2 g (110 mmol) of phenylacetylene (Note 2) and 60 mL of dry tetrahydrofuran (THF) (Note 3). The addition funnel is charged with 60 mL of 2 M isopropylmagnesium chloride (Note... 

A. N-(Benzyloxycarbonyl)-L-methionine methyl ester (2). A 3-L, three-necked, Morton flask equipped with an efficient mechanical stirrer, thermometer, and a dropping funnel is charged with L-methionine methyl ester hydrochloride (117.6 g, 0,66 mol) (Note 1), potassium bicarbonate (282.3 g, 2.82 mol, 500 mol %), water (750 WL), and ether (750 mL), and the solution is cooled to 0°C. Benzyl chloroformate (105... 

A 250 mL Morton flask was equipped with a high-speed, stainless-steel stirrer and a highspeed (20,000 rpm) stirrer motor. In one of the necks of the flask was placed a Claissen adapter holding a West condenser directly over the flask and a 250-mL Hershberg dropping funnel in the outer arm. In the other neck of the flask was placed a second Claissen adapter. 

AIL three-necked Morton flask, equipped with a mechanical stirrer and glass paddle, is charged with sodium metal (1.20g, 52.3 mmol), cut into about —30... 

Catalyst Preparation. Details of the equipment and procedures used were described earlier (13). Essentially, a 2M solution of the alkylaluminum compound in heptane was added gradually to a vigorously stirred 0.38M solution of titanium tetrachloride in a 2-liter Morton-type flask at 20° C. After a desired molar ratio of Al/Ti was reached, an aliquot of the catalyst slurry was withdrawn for testing. The addition of the aluminum compound was then resumed, and the operation was repeated at successive Al/Ti ratios.
