Abstract
Cyclodehydration of α-phenoxy ketones promoted by Eaton’s reagent (phosphorus pentoxide–methanesulfonic acid) is used to prepare 3-substituted or 2,3-disubstituted benzofurans with moderate to excellent yields under mild conditions. The method provides a facile access to benzofurans from readily available starting materials such as phenols and α-bromo ketones. The reaction is highly efficient, which is attributed to the good reactivity and fluidity of Eaton’s reagent. The reaction can be applied to prepare naphthofurans, furanocoumarins, benzothiophenes, and benzopyrans.

Abstract
A simple and flexible synthesis of a new series of 2,4-bis((E)-styryl)quinoline-3-carboxylates (3a-t) has been achieved for the first time in good yields via successive Arbuzov/Horner-Wadsworth-Emmons (HWE) reaction in one-pot using the newly-synthesized ethyl 4-(bromomethyl)-2-(chloromethyl)quinoline-3-carboxylate as the substrate. Our synthetic protocol is as attractive and powerful as it is simple, tolerates a wide range of substituents, and does not involve the use of expensive reagents or catalysts. These title compounds belong to a new class of quinoline derivatives and their antitumor activity was assessed on human cancer cell lines (A549, HT29 and T24). The MTT assay showed compounds 3h, 3k and 3t had significant inhibitory activity with IC50 values of 1.53, 1.38 and 2.36 μM against A549 and 1.50, 0.77 and 0.97 μM against HT29, respectively, much better than the reference cisplatin.

Abstract
In the present investigation, a simple and facile synthetic strategy for the construction of a series of structurally interesting tricyclic-fused N-alkyl-9H-pyrimido[4,5-b]indol-2-amines has been successfully achieved. Our synthesis, based on the annulation reaction between readily available 2-chloroindole-3-carbaldehydes or 3-acetyl-2-chloroindoles and guanidine nitrate using KOH as the base in refluxing EtOH medium, has the attractive features such as mild and economical reaction conditions and easy handing with lesser impact on the environment.

Abstract
A facile and efficient synthesis of novel ethyl 2-(benzofuran-2-yl)-4-phenylquinoline-3-carboxylates and the corresponding acids through the one-pot three-step reaction of ethyl 2-(chloromethyl)-4-phenylquinoline-3-carboxylate with a series of salicylaldehydes is described. It allows an efficient and practical access to some 2-(benzofuran-2-yl)quinolines under transition-metal-free conditions.
