Alkynylations of Oxiranes with Lithium Acetylides by the Catalysis of Trimethylgallium
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 reactions because of low Lewis acidity of trimethylgallium. The mechanism including activation of an oxirane by the coordination to trimethylgallium

Synthesis of clavulones II (1) and III (2) (claviridenones c and b), antitumor marine prostanoids, has been achieved via [3+2] annulation using reaction of (β-(phenylthio)acryloyl)silane 5 with methyl ketone enolate 6 followed by installation of the α-side chain by aldol reaction.
