TL;DR: In this paper, a simple and convenient procedure for the synthesis of aryl-14 H -dibenzo[ a. j ]xanthenes was described through a one-pot condensation of β-naphthol with aryls aldehydes in the presence of sulfamic acid as the catalyst in a solvent-free media using both conventional heating and microwave irradiation.

TL;DR: In this article, a three component coupling of one pot reaction which servers as the most convenient route to the synthesis of benzopyran derivatives using the TiCl4 catalyst (10 mol %) under solvent free conditions is described.

TL;DR: In this article, a convenient procedure for the synthesis of benzo[g]-and benzo [h]chromene derivatives via one-pot three-component condensation of aromatic aldehydes with malononitrile or ethyl cyanoacetate and 1-or 2-naphthol in the presence of 10 mol % of titanium tetrachloride as catalyst is reported.

TL;DR: An efficient and convenient method for the synthesis of substituted coumarins via Pechmann condensation of different phenols with ethylacetoacetate in the presence of ammonium cerium(IV) nitrate as the catalyst in a solvent-free media using both conventional heating and microwave irradiation is described in this article.
