B. Polymeric Urea [Benzene, diethenyl-, polymer with ethenylbenzene, [[[[(1 methylethyl)amino]carbonyt]amino]methyl] deriv.] A 10.0-g. portion of benzylamine polymer beads prepared as in Part A and 125 ml. of tetrahydrofuran (Note 6) are combined in a 300-ml., three-necked, round-bottomed flask equipped with a magnetic stirrer, a dropping funnel, and a condenser fitted with a gas-inlet tube A nitrogen atmosphere is established in the system, and the slurry is stirred while 1.35 g. (0.0159 mole) of isopropyl isocyanate [Propane, 2-isocyanato-] is added. This causes an exothermic reaction, which subsides after about 20 minutes. The mixture is then stirred at room temperature for 22 hours and at reflux for an additional 4 hours. The beads are collected by filtration, washed with 150-ml. portions of tetrahydrofuran (Note 6) and methanol, and dried under reduced pressure over calcium chloride to yield 9.09 g, of the isopropyl urea polymer.

Reaction of lithiodithianes with acyl chlorides, esters or nitriles leads to the formation of 1,2-dicarbonyl compounds in which one of the carbonyl groups is protected as the thioacetal. 476.243.244 Optically active amino ketones of type (69) are inepared via acyl on of dithiane with an oxazoline-prote ed (S)-serine methyl ester (Sch e 41). Optically active (S)-2-alkoxy-l-(l,3-dithian-2-yl)-l-propanenantioselective synthesis of (-)-trachelanthic acid. Enantioselective synthesis of L-glyceraldehyde involves the acylation of a dithiane glycolic acid derivative followed by bakers yeast mediated reduction. ...

The methyl ester of DL-phenylalanine was recovered from its hydrochloride salt and was reduced with LiAlH4 to 3-phenyl-2-amino-l-hydroxypropane. Then 1.0 g such an alcohol (6.6 mmol) was dissolved in 20 mL cold pyridine containing 2.9 g benzenesulfonyl chloride (16.0 mmol) the solution was held at 5°C overnight. Ice was added (50 g) followed by cold 4 N HCl. The resulting solid was collected and crystallized from 95% ethanol to give 1.9 g 3-phenyl-2-benzenesulfonamido-l-(benzene-sulfonyloxy)propane, in a yield of 66%, m.p., 104.5-106.5°C.
