YieldReaction ConditionsOperation in experiment
The central groups in the compound XI are derived, for example, from the following compounds Z3: aliphatic alcohols such as glycerol, 1,2,4-butanetriol, 2-methyl-2-hydroxymethyl-1,3-propanediol, 2-ethyl-2-hydroxymethyl-1,3-propanediol, 1,2,3,4-butanetetrol, pentaerythritol, xylitol, mannitol and sorbitol, ...
Example 14 150 g of L-tartaric add, 700 ml of water and 20 g of Ru Mohr's salt were placed in a 1.3 l stainless steel autoclave and stirred at a hydrogen pressure of 200 bar and 80 C. until the uptake of hydrogen had ended. After cooling of the reaction mixture, removal of the catalyst by filtration and removal of the water by distillation, 123 g of a clear oil were obtained which crystallized overnight at 4 C. The resulting crystalline mass was recrystallized twice from absolute ethanol to give 86 g of L-butane-1,2,3,4-tetraol in the form of a pure-white solid (m.p. 87-88 C.; [alpha]D20 +11.6; c=2, EtOH).
The resulting meso-erythritol preparation was packed and tested in the same manner as in Example 7. As a result, it was found that the preparation had not been solidified at all.

YieldReaction ConditionsOperation in experiment
With toluene-4-sulfonic acid; In toluene; EXAMPLE 29 (2,3-Dihydroxy-1-hydroxymethyl)propyl 4-(n-hexadecylamino)benzoate A mixture of 3.62 g. of 4-(-n-hexadecylamino)benzoic acid, 4.88 g. of <strong>[149-32-6]meso-erythritol</strong>, 7.60 g. of p-toluene sulfonic acid, and 100 ml. of toluene is stirred under reflux for 3 days and the water formed is collected in a Dean-Stark trap. The mixture is partitioned between aqueous sodium carbonate solution and dimethoxyethane. The organic layer is separated, dried over anhyrous magnesium sulfate, and evaporated. Crystallization from chloroform affords (2,3-dihydroxy-1-hydroxymethyl)propyl 4-(n-hexadecylamino)benzoate as a white solid, m.p. 123-125 C.

YieldReaction ConditionsOperation in experiment
With sodium tetrahydroborate;Product distribution / selectivity; Example 1Electrolytic Decarboxylation of Ribonic Acid; Sodium ribonate (15 mmoles) was dissolved in 20 mL of water. Cation exchange resin (Amberlite IRC747 H+ form) was added to lower the pH from 6.8 to 3.5 (or approximately 50% neutralization of the starting material). The solution was filtered to remove the cation resin, the ribonate starting material was diluted to 30 mL, and 25 mL transferred to glass cell for electrolysis. The initial ribonate solution was analyzed by HPLC against a standard and quantified to be 9.54 mmoles (0.38M). The 25 mL of starting material containing 9.54 mmoles of ribonate was stirred in the glass cell, while a constant current of 0.5 amps (100 mA/cm2) was applied. The cell voltage averaged about 6.5 volts, and the pH of the substrate increased from 3.5 to 7.6 after 2 F/mole of charge was passed. Samples were taken at 603, 1206 and 1809 coulombs. The samples containing the erythrose product were reduced to erythritol with an excess amount of sodium borohydride, and analyzed for erythritol by HPLC-RI. The samples were quantified for erythritol based on a response factor determined from an erythritol standard, see Table 1.; Example 2 Electrolytic Decarboxylation of Arabinonic Acid; Potassium arabonate (15 mmoles) was dissolved in 20 ml of water. The arabonate was acidified to approximately 50% neutralization by adding cation exchange resin (Amberlite IRC747 H+form) and lowering the pH from 8.4 to 3.5. The arabonate was filtered to remove the resin, diluted to 30 mL, and transferred to a glass cell for electrolysis. The initial arabonate was quantified by HPLC-RI against an arabonate standard and was found to contain 9.2 mmoles (0.37M). There was a loss of 3.3 mmoles of arabonate from the cation exchange resin.The 25 mL of starting material containing 9.2 mmoles of arabonate was stirred in the glass cell, while a constant current of 0.5 amps (100 mA/cm2) was applied. The cell voltage averaged about 5.5 volts, and the pH of the substrate increased from 3.5 to 7.7 after 2 F of charge was passed per mole of starting material. Samples were taken at 603, 1206 and 1809 coulombs. The samples containing erythrose were reduced to erythritol with an excess amount of sodium borohydride, and analyzed for erythritol by HPLC-RI. The samples were quantified for erythritol based on a response factor determined from a known standard, see Table 2.
