An efficient and BF3·Et2O-catalyzed chemoselective synthesis of diversified 1,3-diarylisobenzofuran in a high yield has been described. The reaction proceeds through sequential hydroarylation–cyclization between 2-formylarylketones and electron-richarenes/heteroarenes. Advantageous features of the developed methodology include operational simplicity, a broad substrate scope, and applicability towards

Facile synthesis of 1-substituted 4-H phthalazine, a versatile scaffold for chemically diverse phthalazines
An improved synthetic strategy for 1-substituted 4-H phthalazines using a convenient, three-step reaction sequence under mild conditions is described. The protocol involves condensation of hydrazine hydrate with o-ketobenzaldehydes derived through the Pb(OAc)4 oxidation of the N-acylhydrazones of salicylaldehydes. This pathway is of high practical value since a wide variety of substituted acylhydrazides
