Abstract
“Deficient” but “efficient”, the first example of catalytic Friedel-Crafts alkylation of arenes, carrying electron-withdrawing groups, with alcohols is reported. The optmized iron(III) chloride (97%) FeCl3 catalyzed allylation, benzylation and propargylation procedures opened access to a range of tetrahydro-naphthalenes, tetrahydro-isoquinolines and tetrahydro-benzo[d]azepines featuring tertiary benzylic stereocenters in excellent yields (up to 92%) and short reaction time.File in questo prodotto:
