, p. 1810 - 1813 (2007/10/02)
The reaction of 1-lithio-1-alkynes with oxiranes under the catalytic action of trimethylgallium afforded the corresponding β-hydroxy acetylenic compounds in good yields with excellent regioselectivities.No isomerization of oxiranes was observed during the
Synthesis of Substituted Furans by Palladium-Catalyzed Cyclization of Acetylenic Ketones
Fukuda, Yukitoshi,Shiragami, Hiroshi,Utimoto, Kiitiro,Nozaki, Hitosi
, p. 5816 - 5819 (2007/10/02)
Palladium-catalyzed cyclization of β,γ-acetylenic ketones gives furans by intramolecular oxypalladation and subsequent protodemetalation. 3-Allylfurans were exclusively obtained by trapping the intermediate 3-furylpalladium species with allyl halides in t
THE CATALYTIC ACTION OF TRIMETHYLGALLIUM ON THE REACTION OF ALKYNYLLITHIUM WITH EPOXIDES
Utimoto, Kiitiro,Lambert, Claude,Fukuda, Yukitoshi,Shiragami, Hiroshi,Nozaki, Hitosi
, p. 5423 - 5426 (2007/10/02)
Trimethylgallium catalyzes the reaction of 1-lithio-1-alkynes with epoxides affording 3-alkyn-1-ols in good to excellent yields.
