实验步骤: M36 was prepared with 3,5-di-t-butyl-4-hydroxybenzaldehyde and sulfonyl diacetonitrile under similar conditions as described for M27.

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of (0.5 g) of 2-nitrothiophen-5-carboxaldehyde and (0.7 g) of sulfonyl diacetonitrile in 6 mL ethanol was refluxed with a few drops of piperidine for 4 hours. Ethanol was removed in a rotavap and the mixture worked up with ethylacetate, diluted acid and brine. A portion of the crude was then purified by HPLC on a C-18 column to provide (0.05 g) of (E)-2-cyanomethylsulfonyl-3-(2-nitrothien-5-yl)acrylonitrile along with (0.03 g) of (E,E)-2-[[1-cyano-2-(2-nitrothien-5-yl)ethenyl]sulfonyl]-3-(2-nitrothien-5-yl)acrylonitrile. Ethanol was removed in a rotavap diluted acid and brine A portion of the crude was then purified by HPLC on a C-18 column

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 500 mg of 5-bromo-3,4-dihydroxybenzaldehyde and 700 mg of sulfonly diacetonitrile in 6 ml of ethanol was refluxed with few drops of piperidine for 4 hours. Ethanol was removed in rotavap and the mixture worked up with ethyl acetate, diluted acid and brine. A portion of the crude was then purified by HPLC on a C-18 column to provide about 50 mg of 2-(3-bromo-4,5-dihydroxyphenyl)-1-cyano-1-cyanomethylsulfonly ethene. Ethanol was removed in rotavap diluted acid and brine A portion of the crude was then purified by HPLC on a C-18 column

实验步骤: A mixture of 500 mg of 3,5-diisopropyl-4-hydroxybenzaldehyde and 700 mg of sulphonyl diacetonitrile in 6 ml of ethanol was refluxed with a few drops of piperidine for 4 hours. Ethanol was removed in a rotavap and the mixture worked up with ethyl acetate, diluted acid and brine. A portion of the crude was then purified by HPLC on a C-18 column to provide 50 mg of the titled compound along with 30 mg of (E,E)-2-[[1--Cyano-2-(3,5-diisopropyl-4-hydroxyphenyl)ethenyl]sulfonyl]-3-(3,5-diisopropyl-4-hydroxyphenyl)acrylonitrile.
