YieldReaction ConditionsOperation in experiment
35% With phosphoric acid; ruthenium-carbon composite; hydrogen; In water; at 150℃; under 60006.0 Torr; for 21h; as a metal-supported catalyst, ruthenium carbon having a dispersity of 17.46percent, a metal surface area of 63.78 (m 2 / g), a particle diameter of 7.73 (nm), and a metal loading of 5percent A catalyst was prepared.In a pressure vessel, 100 g of water, 3.2 g of glutamic acid, 2.86 g of phosphoric acid and 0.16 g of ruthenium carbon catalyst were mixed. The mixture was stirred for 16 hours while pressurizing at 180 ° C. to a hydrogen pressure of 8 MPa. After completion of the reaction, the reaction mixture was filtered. When the components contained in the filtrate were analyzed by LC (liquid chromatography), prolinol was obtained in a yield of 35percent. Prolinol was synthesized under the same conditions as in Example 1. However, instead of glutamic acid, 2.8 g of pyroglutamic acid was used as a raw material. The reaction temperature was 150 ° C., and the reaction time was 21 hours. The yield of prolinol was 35percent.

YieldReaction ConditionsOperation in experiment
Compounds 41-70 were part of a parallel set prepared in library plate format according to General Procedure L, outlined below. ; L. General Procedure for Plate Preparation-Amide Formation XXI: Resin bound deprotected biarylphenol XVII (prepared from intermediate XII, boronates XIVd and XIVe, following general procedures D-F) was distributed into a 96 well plate, 10 mg of resin (0.013 mmol) per well. To the resin 400 mul of dichloromethane was added, followed by 100 mul of DIEA, followed by 0.13 mmol (10 equiv) of heterocyclic carboxylic acid XXa-XXn was added followed by 61 mg (0.13 mmol, 10 equiv) of PyBrop. The plate was shaken at room temperature for 24 hours, then drained and washed with dichloromethane, methanol/dichloromethane, dimethylformamide, methanol/dichloromethane and dichloromethane. The compounds were cleaved with TFA/dichloromethane (600 mul, 1:1) into a 96 deep well plate and submitted for testing without further purification. (Mass spec results obtained are shown in Table 4).
