Reactions of styryl and phenylethynyl sulfones with some CH-acids
摘要:
Reactions of methyl and p-tolyl phenylethynyl sulfones with enolated of dimethyl malonate and malononitrile lead to the formation of sulfonyl-substituted derivatives of ethylidenemalonic acid. Methyl (E)-beta-styryl sulfone reacts with sodium enolates of dimethyl malonate, malononitrile, and methyl cyanoacetate to give common Michael adducts.
