  Oligocyclopropane Structural Units from Cationic Intermediates

  摘要：

  [GRAPHICS]syn- and anti-bis-cyclopropanes have been efficiently prepared through two distinct routes via the trapping of cyclopropylcarbinyl cationic intermediates. A ring-closing olefin metathesis for the formation of the necessary allylsilane precursors highlights the initial route. The cyclopropanation step proceeds in good yield to provide exclusively trans-vinylcyclopropanes. Iteration of the sequence has provided an efficient route to bis-cyclopropanes. The stereospecificity of the second cyclization was shown to be dependent on distal functionality. An alternative approach produces these interesting structural units from skipped dienes in a single step.

  This paper describes the ring-closing metathesis of silyl ether connected dienes using molybdenum and ruthenium alkylidene catalysts. The cyclizations proceed to afford the corresponding cyclic silyloxy olefins in good to excellent yields. Subsequent oxidative ring cleavage yields highly functionalized olefins.
