Cyclopenta[b]pyridine Usage And Synthesis

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.
