Diastereoselective Synthesis
of Seven-Membered-Ring trans-Alkenes from Dienes and Aldehydes by Silylene Transfer
Posted on 2016-02-20 - 16:06
Silver-catalyzed silylene transfer to alkenes forms vinylsilacyclopropanes
regioselectively. These allylic silanes undergo additions to aldehydes
to form seven-membered-ring trans-alkenes with high
diastereoselectivity. The high reactivity of the trans-alkenes is evidenced by their formal [1,3]-sigmatropic rearrangement
reactions and the rapid additions of oxygen–hydrogen bonds
across the carbon–carbon double bonds.
