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.
