titleOfInvention | Synthetic method of 3+2 closed ring |
abstract | The invention discloses a synthesis method of a 3+2 ring closure, which strengthens chiral induction through the spatial stereo effect of bridge ring molecules, so that the ring closure reaction has specific and high-efficiency spatial selectivity. The method is applied to synthesis of peramivir and has the characteristics of short synthetic route, high stereoselectivity and simple and convenient operation process. |
