isomerization of cyclic 3-cyclopropyl ketones under FVP conditions at 620 °C provides a new and convenient route to δ,ε-unsaturated cycloalkanones. The synthetic potential of this novel three-carbon ring expansion has been demonstrated by the synthesis of (±)-muscone from inexpensive C-12 starting material.
在FVP条件下于620°C进行的环状3-环丙基酮的热异构化为δ,ε-不饱和环烷酮提供了一条新的便捷途径。由廉价的C-12起始原料合成(±)-麝香酮已证明了这种新颖的三碳环扩环的合成潜力。
