Cyclopenta[b]pyridine Chemical Properties,Usage,Production

Chemical Properties

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 300C and atmospheric pressure from glycerol, cyclopentanone, and ammonia over a modified alumina catalyst (3%Cu/2%Ti/-AlO). Glycerol conversion is 70.3% with 81.6% selectivity to 2,3-cyclopentenopyridine.
