A new synthetic method of coumarins 3-aldehyde via visible light stimulation and oxidation promotion cascade radical cyclization/hydrolysis process is reported, with good to excellent yields and valuable synthetic applications.
New synthetic method of coumarins 3-aldehyde via visible light stimulation and oxidation promotion cascade radical cyclization/hydrolysis process is reported. this reaction involves a two-step procedure, the 1,3-dioxolane radical is initiated in situ from 1,3-dioxolane via the excited Ru(bpy)(3)Cl-2 and oxidant TBHP, subsequently an addition to triple bond of various alkynes produces vinyl radicals, the radical intermediates can smoothly convert to coumarin 3-aldehyde via tandem cyclization/acidic hydrolysis process in good to excellent yields. Furthermore, the synthetic application valuable of coumarin 3-aldehyde is also evaluated in this work.
