Gharpure, Santosh J,Prasath
, p. 943 - 949 (2011)
An intramolecular, alkyne Prins type cyclization of vinylogous carbonates derived from o-alkynyl phenols is developed for the stereoselective construction of trans-2,3-disubstituted dihydrobenzofuran derivatives. Strong Lewis acids like TMSOTf catalyse th
