A new synthetic route was developed via the nucleophilic addition of lithium alkynylide to 1-arylsulfonyl cyclopropanol 1 to afford 1-alkynyl cyclopropanol, which then reacted with aryl iodide to construct trisubstituted cross-conjugated dienones through

An efficient one-pot process to construct a series of polyfunctionalized propargylic alcohol derivatives from the simple materials without functional protection was investigated. A solution of nBuLi in hexane was added into dry THF by syringe the resulting solution was then maintained at RT for 3 hours. the freshly prepared lithium enolate of acetaldehyde was used directly in the reaction. The nBuLi was added over a period of 30 minutes by syringe to a solution of terminal alkyne in THF at -30°C. The scope and limitations of the reaction was explored by examining other terminal alkynes. A number of different carbonyl-containing substrates were also examined. It was observed that propargylic alcohol derivatives are important synthetic intermediates in organic synthesis.
