A catalytic formal ene reaction between ketone-derived silyl enol ethers and terminal alkynes is described. This transformation is uniquely capable of bimolecular assembly of 2-siloxy-1,4-dienes and can be used to access β,?-unsaturated ketones containing quaternary carbons in the α-position.

A triflic imide (Tf2NH) catalyzed isomerization of kinetically favourable silyl enol ethers into thermodynamically stable ones was developed. We also demonstrated a one-pot catalytic reaction consisting of (2 + 2) cycloaddition and isomerization. In the reaction sequence, Tf2NH catalyzes both of the reactions.

Triisopropylsilyl enol ethers react with (TsN)2Se to give α-N-tosylamino derivatives in modest to good yields.In the absence of 1,3-diaxial interactions the N-tosylamino group prefers an axial conformation.The axial N-tosylamino derivatives can be readily transformed into the azabicyclononane skeleton, the core structure of a number of alkaloids.
