Resumen
A controlled photorelease of alkynoic acids from the meso-methyl
BODIPY photoremovable protecting group facilitates their subsequent
efficient decarboxylation to give terminal alkynes for a CuI-catalyzed
azide/alkyne cycloaddition. The quantum efficiencies of the photochemical
step and the kinetics of the click reaction step are reported
