Stereoselective polycyclisations of allyl and enyne silanes: Evidence for bicyclo[3.2.0]hept-1(7)ene structure

The intramolecular copper(I)-catalyzed [2 + 2]-photocycloaddition of diphenyldiallysilane (1) (or tetraallylsilane (4)) led to sila-3-bicyclo[3.2.0]heptane (3) (or to spiro analogous 6) in the cis (or cis-cis) configuration whereas the α,ω-diiodide (2) obtained by cyclozirconation of 1 (or from the homologous tetraiodide 5) followed by addition of n-BuLi, produced the sila-3-bicyclo[3.2.0]heptane (3) (or to the spiro analogous 6) in the trans (or trans-trans configuration). The same cyclozirconation reaction, starting from the hetero enyne 7, selectively led to the highly strained silacyclobutene moiety 15 which represents the first stable hetero bicyclo[3.2.0]hept-1(7)ene skeleton, hypothetical intermediate in methathesis reactions.
