The first fluoroalkylated 1,3-bis(silyloxy)-1,3-butadienes have been prepared. Their reaction with oxalyl chloride provides a convenient approach to fluoroalkylated gamma-alkylidenebutenolides. (c) 2010 Elsevier Ltd. All rights reserved.
Regioselective synthesis of 4-alkyl- and 4-aryl-6-(perfluoroalkyl)salicylic acid derivatives by formal [3+3] cyclocondensation of 1,3-bis(silyloxy)-1,3-butadienes with 3-silyloxy-1-(perfluoroalkyl)prop-2-en-1-ones
4-Alkyl- and 4-aryl-6-(perfluoroalkyl)salicylic acid derivatives were regioselectively prepared by [3+3] cyclization of 1,3-bis(silylenolethers) with 3-silyloxy-1-(perfluoroalkyl)prop-2-en-1-ones.
