CLEAR COLORLESS TO BROWNISH LIQUID | [Uses]
2,?3-?Cyclopentenopyridine is used as reactant/reagent for ruthenium-mediated dual catalytic reactions of isoquinoline via C-H activation and dearomatization for isoquinolone. | [General Description]
The structural properties of 2,3-cyclopentenopyridine using spectroscopic and computational techniques have been studied. 2,3-Cyclopentenopyridine is present in the side chain of cefpirome (HR 810), a new cephalosporin. | [Synthesis]
Synthesized by gas-phase reaction in a fixed-bed reactor at 300°C and atmospheric pressure from glycerol, cyclopentanone, and ammonia over a modified alumina catalyst (3%Cu/2%Ti/γ-Al₂O₃). Glycerol conversion is 70.3% with 81.6% selectivity to 2,3-cyclopen |
