Sequential one-pot method for oxy-Michael addition, Heck coupling, and degradation followed by condensation: facile synthesis of 2-benzoxepin-3(1H)-ones

Sequential one-pot approach for the synthesis of functionalized phthalans via Heck-reduction–cyclization (HRC) reactions

An efficient and practical method is described for the direct synthesis of 1,3-dihydroisobenzofurans, an important structural motif present in biologically active natural or synthetic compounds.

Lewis acid promoted C–C and copper-catalyzed C–O bond formation: synthesis of neoflavans

An intramolecular [Cu]-catalyzed C–O bond formation for the synthesis of neoflavans is presented.

An efficient synthesis of highly substituted indanones and chalcones promoted by superacid

A superacid promoted one-pot method was developed for the efficient synthesis of indanones. This process enabled the formation of a dual C–C bond between the aryl isopropyl ketones and benzaldehydes. Interestingly, when the reaction was performed between acetophenones and benzaldehydes, it was impeded after the aldol condensation and resulted in the corresponding chalcones.
