Some of the applications of 3-butynoic acid are:
- Synthesis of functionalized γ-butyrolactones and tetrahydrofurans via Conia-ene cyclizations.
- Synthesis of allenoates for [2+2] cycloadditions with alkenes.
- Phosphine-catalyzed synthesis of highly functionalized coumarins.
- Synthesis of various useful organotin reagents via radical hydrostannation of 3-butynoic acid.
