resulting diastereomers was determined by 1H NMR spectroscopy. It was found that some parameters such as the chain length of nitroalkyl and the nature of aromatic aldehyde play the main role in affecting the diastereomeric ratio on the surface of MMPNs. Certain trends have been analyzed from the data, and it can be inferred that some aldehydes approximately prefer the formation of anti diastereomers as the

A convenient and rapid method for the synthesis of symmetrical disulfides from alkyl or aryl alkyl halides using sulfurated borohydride exchange resin (SBER) under anhydrous conditions is described. Selective transfer of sulfur to an alkyl group rather than an aryl group is achieved using this methodology.

Synthesis of novel amides and esters prodrugs of olmesartan is described. Their in vitro stability in rat plasma was tested. The results showed that the ester derivative IIa with n-octyl substituted dioxolone moiety was rapidly converted into olmesartan within 30 min. The pharmacokinetic parameters of IIa were studied and compared with those of olmesartan medoxomil. Compound IIa is proposed to be a promising prodrug of olmesartan.
