- Synthesis of N-alkylimidazolium salts and their utility as solvents in the Beckmann rearrangement
-
Six different room temperature ionic liquids (RTILs) based on N-methyl or N-isopropyl imidazolium cations with counteranions, such as BF4-, PF6-, and OTf-, have been synthesized by exchanging the counteranions of the corresponding N-methyl or N-isopropylimidazolium bromides using appropriate salts such as NH4BF4, KPF6, and AgOTf. Catalytic amounts of these ionic liquids (ILs) have been used as the reaction medium for the Beckmann rearrangement of oximes to amides in the presence of PCl5. A moderate to good conversion of oximes to amides in all the six ILs was observed.

- TRIAZOLE DERIVATIVES AS INHIBITORS OF 11-BETA HYDROXYSTEROID DEHYDROGENASE-1
-
Triazole derivatives of structural formula I are selective inhibitors of the 11β-hydroxysteroid dehydrogenase-1. The compounds are useful for the treatment of diabetes, such as noninsulin-dependent diabetes (NIDDM), hyperglycemia, obesity, insulin resistance, dyslipidemia, hyperlipidemia, hypertension, Metabolic Syndrome, and other symptoms associated with NIDDM.
