The synthesis of saturated bis-spiroacetal (11) from an intramolecular catalysed cyclization of a keto-epoxide together with the preparation of unsaturated bis-spiroacetal (16)via a Barton-type reaction of substituted hydroxy spiroacetal (15) highlight a means of constructing the above-named ring system.
分子内催化的酮环氧化物的环化反应合成饱和双螺缩醛(11)以及通过取代羟基螺缩醛的Barton型反应制备不饱和双螺缩醛(16)(15)突出了一种构建方法上面提到的铃声系统。
