First synthesis of 4-(arylsulfonyl)phenols by regioselective [3+3] cyclocondensations of 1,3-bis(silyloxy)-1,3-butadienes with 2-arylsulfonyl-3-ethoxy-2-en-1-ones
The formal [3+3] cyclization of 1,3-bis(silyloxy)-1,3-butadienes with readily available 2-arylsulfonyl-3ethoxy-2-en-1-ones resulted in regioselective formation of 4-(arylsulfonyl)phenols. (C) 2008 Elsevier Ltd. All rights reserved.
