Cyclocondensation of unsymmetrical perfluoroalkyl-substituted β-diketones with urea, thiourea, and guanidine
The reactions of unsymmetrical perfluoroalkyl-substituted β-diketones with guanidine, urea, and thiourea gave the corresponding 2-amino-, 2-hydroxy-, and 2-sulfanyl-6-perfluoroalkyl-4-methylpyrimidines.
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(silyl enol ethers) with 3-silyloxy-1-(perfluoroalkyl)prop-2-en-1-ones.
