ing set to predict oral absorption, carboxylic acids and basic compounds had to be treated separately by experimental immobilized artificial membrane chro- matography. These conclusions remind us that to build a model suitable for oral absorption predic- ...
This suggests the deprotonation of carboxylic acid leading to the formation of carboxylate during the course of the reaction. The C-O-C stretch of epoxide at 1046 cm−1 (region a)46 also become weaker compared to fresh 3xGO, clearly suggesting the direct participation of both the ...
Synthesis of substituted benzocyclobutenediones Hitherto unknown cis - and trans -3-alkyl- and 3-aryl-3-fluorocycobutylamines have been synthesised selectively from 3-oxocyclobutane carboxylic acid in si... LS Liebeskind,LJ Lescosky,CM Mcswain - 《Journal of Organic Chemistry》 被引量: 179发表:...
Esterification of carboxylic acids with alcohols is one of the most important reactions in organic synthesis[1]. Long chain fatty acid alkyl (especially methyl and ethyl) esters can be used as certain biofuel, which is of good interest. The biofuel is mainly synthesized through transesterification ...
These properties have found catalytic application in, for example, the isomerization of glucose to fructose [1], and the synthesis of dimethyl carbonate [2]. The chemical functionalization of zirconia surfaces with sulfate ions to generate SO4/ZrO2 (SZ) solid acid catalysts has attracted significant...
As expected both AM1 and PM5 estimated that the zwitterionic structure 31a of 3-pyridinecarboxylic acid 31 is much more stable than the 3-carboxypyridine structure 31b, which is consistent with the experimental finding [22]. Basicity It is well known that it is impossible to measure the pKa ...
