Solvent free, microwave assisted conversion of aldehydes into nitriles and oximes in the presence of NH2OH · HCl and TiO2
Aromatic aldehydes bearing electron-donating groups are easily converted into their respective nitriles using NH2OH · HCl and TiO 2 under microwave irradiation, while those bearing an electron-withdrawing group give the corresponding oximes.

An efficient chemoselective etherification of phenols in polyfunctional aromatic compounds
A simple and efficient chemoselective alkylation of phenols in polyfunctional aromatic compounds with different alkyl halides in the presence of K2CO3/TBAB is reported. The method is successful with various hydroxy aromatic acids or oximes possessing other functional groups.

Synthesis of new 4,5-dihydroisoxazoles with potential anti-inflammatory activity
This paper reports the synthesis of different 4,5-dihydroisoxazoles which may present anti-inflammatory activity. The methodology employed was based on the 1,3-dipolar cycloaddition of nitrile oxide derived from vanillin to unsaturated compounds. It was u
