4-PENTYNOIC ACID Chemical Properties,Usage,Production

Chemical Properties

white to beige crystalline powder or flakes

Uses

4-Pentynoic Acid is a hypoglycemic agent shown to increase liver tyrosine aminotransferase and plasma corticosterone while decreasing blood sugar in rats.

Uses

4-Pentynoic acid was used:

  • as building block for the synthesis of library of eight sequence-defined model oligomers
  • in one-pot synthesis of the complex polycyclic heterocycles benzo[4,5]imidazo[1,2-c]pyrrolo[1,2-a]quinazolinone derivatives
  • in the synthesis of various allenenols lactones [5(E)-(2-allenylidene)-tetrahydro-2-furanones]
  • in the synthesis of a cyctotoxic macrolide by ring-closing metathesis of a bis acetylene

General Description

4-Pentynoic acid undergoes copper-catalyzed intramolecular cyclizations to form enol lactones. It also reacts with 1-bromo-1-alkynes in the presence of a Pd catalyst to yield biologically active ynenol lactones.
