An Efficient Synthesis of 3-(1H-Tetrazol-5-yl)coumarins (=3-(1H-Tetrazol-5-yl)-2H-1-benzopyran-2-ones) via Domino Knoevenagel Condensation, Pinner Reaction, and 1,3-Dipolar Cycloaddition in Water
A novel straightforward synthesis of 3‐(1H‐tetrazol‐5‐yl)coumarins (=3‐(1H‐tetrazol‐5‐yl)‐2H‐1‐benzopyran‐2‐ones) 6 viadominoKnoevenagelcondensation, Pinnerreaction, and 1,3‐dipolar cycloaddition of substituted salicylaldehydes (=2‐hydroxybenzaldehydes), malononitrile (propanedinitrile), and sodium azide in H2O is reported (Scheme 1 and Table 2). This general protocol provides a wide variety of

Coumarin derivatives of the general formula:
wherein R is hydrogen atom, an alkyl group or an alkenyl group, R1 is hydrogen atom, an alkyl group, an alkenyl group or an alkoxyl group, and the OR and R1 groups each are substituted at any of the 5,6, and 8 positions of the coumarin ring, and the salt thereof. The compounds are useful as antiallergic agent for preventing and treating allergic diseases.
