Reaction of N-tosylated imines with α,β-acetylenic ketones via organozinc species

Liu, Yong-Kang,Wu, Quan-Ping,Guo, Qing-Xiang,Xue, Song

experimental part, p. 1944 - 1953 (2010/09/05)

A new procedure for stereoselective synthesis of trisubstituted alkenes by an one-pot, three-component reaction of N-tosylated imines with,-acetylenic ketones and organozinc species CF3COOZnEt was described. This reaction system provides-branched Morita-Baylis-Hillman adducts with excellent yields in absence of any catalyst. Copyright
