The valuable tetrahydro-?- and ?-carboline skeleta can be accessed through Pictet-Spengler cyclisation initiated by acceptorless dehydrogenation of saturated cyclic amines. substrate scope for the ?-isomers is found to somewhat limited, but access ?-isomers more reactive 2-(aminoethyl)indoles general. synthetic utility hydrogen transfer catalysis highlighted in a two-step preparation alkaloid d...

Supported vanadia catalyst was successfully synthesized using wet impregnation of gamma-Alumina to study Propane Oxidative Dehydrogenation (POD). The prepared catalysts were characterized with XRD, BET, and TPR tests. In a broad temperature range (340 to 630°C), effects of vanadia loading (2.7, 5.4, and 9 wt%) and propane to oxygen ratio (3/1 to 1/3) were investigated on propane conversion as w...
