An efficient synthetic procedure for the preparation of a diverse library of 1,3-benzodioxoles was developed by applying controlled microwave heating in comparison with currently available conventional heating. Reactions were completed in less than 3 h. The isolation of product is simple, the isolated yields are good to excellent, and this method is applicable to large scale production.

A series of 2-substituted and 2,2-disubstituted 1,3-benzodioxoles have been synthesised by reaction of catechol and pyrogallol with corresponding aldehydes and ketones catalysed by montmorillonite KSF or K-10. The reactions are completed within 2.7-24 h to give satisfactory yields. Ketones give better yields than aldehydes, although highly sterically hindered ketones and diaryl ketones fail to react at all.
