A preparative procedure was developed for the synthesis of 4-[5-(1-R-1H-indol-3-ylmethylidene)-4-oxo-2-sulfanylidene-1,3-thiazolidin-3-yl]butanoic acids which were converted to acid chlorides, and the latter reacted with aromatic and heterocyclic ami

An alternative methodology for the synthesis of chiral 3-(p-tolyl) butanoic acids is presented. This was accomplished through the diastereoselective hydrogenation reaction of different chiral N-3-(p-tolyl) but-2-enamides, using Pd/C in EtOH, to produ

[EN] The kinetics of the ketonic decarboxylation of linear and branched carboxylic acids over m-ZrO2 as a catalyst has been investigated. The same apparent activation energy is experimentally determined for the ketonic decarboxylation of both linear

S1P1 receptor driven lymphopenia has proven utility in the treatment of an array of autoimmune disease states. As a part of our efforts to develop potent and selective S1P1 receptor agonists, we have identified a novel chemical series of 4-oxo-4-(5-(
