Description

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.
