Merrifield MicroTube(TM) reactors for solid phase synthesis

Polystyrene grafted polypropylene MicroTube(TM) reactors (length x OD, 25 x 5 mm) have been functionalized with chloromethyl groups (Merrifield- type) using chloromethyl methyl ether and Lewis acid catalysts. A potentiometric method using a chloride ion selective electrode has been developed to measure the loading of the Merrifield MicroTube(TM) reactors. A typical loading of 25-35 μmol/tube for Merrifield MicroTube(TM) reactors has been achieved. Several reactions performed on Merrifield MicroTube(TM) reactors demonstrated that they are excellent supports for solid phase synthesis. As a result of the ease with which radiofrequency memory tags can be associated with and separated from the supports, these MicroTube(TM) reactors can facilitate the synthesis of combinatorial libraries.
Studies and synthesis of substituted 4-biphenyl acetamide derivatives

A new series of substituted 4-biphenylamides have been synthesized by condensation of 4-biphenyl acetic acid with different primary amines (aromatic and aliphatic). 4-Biphenyl acetic acid was first treated with thionyl chloride in dry benzene to prepare substituted 4-biphenyl acetyl chloride, which is then treated with different aliphatic or aromatic amines to synthesize various substituted 4-biphenyl acid-amide derivatives. The structure of newly synthesized compounds has been established by analytical and spectral methods. These synthesized compounds have shown antifungal properties against Fusarium udum and Curvularia lunata.
An improved synthesis of the selective matrix metalloproteinase inhibitor, Ro 28-2653

An efficient synthesis of Ro 28-2653, a selective matrix metalloproteinase inhibitor, has been developed. The title compound was prepared in four steps and 76% overall yield from 4-biphenylacetic acid. The key, barbituric acid formation step was significantly improved by using 2-propanol and potassium tert-butoxide as the solvent and base, respectively, instead of the typical ethanol and sodium ethoxide combination.
