Abstract
The regioselective allylation of 4-silyloxyquinolinium triflates with allyl tri-n-butyltin has been performed to give 2-allyl-4-silyloxy-1,2-dihydroqui nolines with excellent yields. Similiar results have been obtained with 4-s ilyloxy-l-benzopyrylium triflates and 4-silyloxy-1-benzothiopyrylium trifla tes. (C) 2001 Elsevier Science Ltd. All rights reserved.
