An umpolung strategy has been developed for the synthesis of β,γ-unsaturated ketones utilizing nucleophilic β-alkenylation of N-alkoxyenamines, which are prepared in situ from ketones and isoxazolidine, with alkenyl aluminum reagents. Various β,γ-unsaturated ketones have been prepared following this simple procedure under mild conditions.
已经开发了一种利用N-烷氧基烯胺的亲核性β-烯基化反应合成β,γ-不饱和酮的化学对策,N-烷氧基胺是通过烯基铝试剂由酮和异恶唑烷原位制备的。按照这种简单的方法,在温和的条件下已制备了各种β,γ-不饱和酮。
