1,4-Benzodioxan-6-carboxaldehyde finds its uses as building block in the synthesis of tetrahydroisoquinolinones, in the preparation of benzofuran analog, a potential inhibitor of CAMP-specific phosphodiesterase type IV, in the synthesis of (5Z)-5-(2,3-dihydro-1,4-benzodioxan-6-ylmethylene)-1-methyl-2-thioxoimidazolidin-4-one. It was screened as a fragment for inhibitors of PDEA using enthalpy arrays and X-ray crystallography. 1,4-Benzodioxane-6-carboxaldehyde have also been used as an intermediate in the synthesis of a new class of Dopamine D3 and D4 receptor antagonists.
