Abstract: We developed an easy, In(OTf)3-catalysed, regioselective and generalizable method, for allylation/cyclization of β-ketolactone-type heterocyclic compounds. This reaction is proposed to proceed one-pot, through a Friedel–Crafts C-allylation followed by cyclization. This process represents a green synthetic… read more here.

Abstract: A simple and efficient method for the synthesis of 1,1-diarylalkanes via the Friedel–Crafts-type alkylation reaction of electron-rich arenes with cinnamic acid ester derivatives or chalcones is reported. Iron triflate has been found to be the… read more here.
