Stereo- and regiocontrol in ene-dimerisation and trimerisation of 1-trimethylsilyl-3-phenylcyclopropene

Sheshenev, Andrey E.,Baird, Mark S.,Bolesov, Ivan G.,Shashkov, Alexandre S.

experimental part, p. 10552 - 10564 (2010/03/01)

1-Trimethylsilyl-3-phenylcyclopropene and its 2D-analog undergo a highly stereocontrolled ene-reaction to give a single dimer. Further reaction leads to one or more trimers derived through two ene-reactions. The dimer formed easily undergoes cycloaddition
