- Base-Promoted Tandem Synthesis of 2-Azaaryl Tetrahydroquinolines
-
A novel method to synthesize 2-azaaryl tetrahydroquinolines by the base-promoted tandem reaction of azaaryl methyl amines and styrene derivatives is reported (over 30 examples, yields up to 95%). Mechanistic probe experiments demonstrate that the deprotonation of the benzylic C-H bond and the addition to the styrene vinyl group proceeds via the SNAr mechanism.

- Copper-Catalyzed Oxidative Difunctionalization of Terminal Unactivated Alkenes
-
The copper(II)-promoted free-radical oxidative difunctionalization of terminal alkenes to access ketoazides by utilizing molecular oxygen has been reported. A series of styrene derivatives have been evaluated and were found to be compatible to give the desired difunctionalized products in moderate to good yields. The role of molecular oxygen both as an oxidant and oxygen atom source in this catalytic transformation has been unquestionably demonstrated by 18O-labeling studies and a radical mechanistic pathway involving the oxidative formation of azidyl radicals is also designed. This environment-friendly catalytic oxidative protocol can transform aldehyde to nitrile.

- Prostaglandin endoperoxide H synthase biosynthesis inhibitors
-
The present invention describes pyridazinone compounds of formula I which are cyclooxygenase (COX) inhibitors, and in particular, are selective inhibitors of cyclooxygenase-2 (COX-2). COX-2 is the inducible isoform associated with inflammation, as opposed to the constitutive isoform, cyclooxygenase-1 (COX-1) which is an important “housekeeping” enzyme in many tissues, including the gastrointestinal (GI) tract and the kidneys. The selectivity of these compounds for COX-2 minimizes the unwanted GI and renal side-effects seen with currently marketed non-steroidal anti-inflammatory drugs (NSAIDs).
