  Ring Contraction of Cyclobutanes and a Novel Cascade Reaction: Application to Synthesis of (.+-.)-Anthoplalone and (.+-.)-Lepidozene

  摘要：

  Two efficient and practical synthetic methodologies for the construction of small ring systems have been developed. The first method involves a novel rearrangement of cyclobutanes 10 and 14 leading to cyclopropanes 11 and 15 employing BF3.OEt(2) or POCl3 in the presence of pyridine or Raney nickel. The second method utilizes a novel cascade reaction of alpha,beta-unsaturated esters 25 and 36 possessing a cyclopropyl ketone moiety with TMSI in the presence of(TMS)(2)NH to afford polycyclic cyclobutane derivatives 26 and 38. A synthesis of(+/-)-anthoplalone (41) and a formal synthesis of (+/-)-lepidozene (42) were achieved utilizing 15, obtained by the above method.

• Preparation of olefins and acetylenes via reductive elimination with SmI2-HMPA

  Reaction of β-hydroxy or acetoxy sulfones with Sml2 in the presence of HMPA caused effectively reductive elimination to provide olefins. Treatment of enol phosphates, readily synthesized from β-hydroxy sulfones via keto sulfones, under the same conditions efficiently produced mono- and disubstituted acetylenes.

  在HMPA存在下，β-羟基或乙酰氧基砜与Sml 2的反应引起有效的还原消除，从而提供了烯烃。在相同条件下处理由β-羟基砜通过酮砜轻松合成的烯醇磷酸酯，可以有效地生产单取代和二取代的乙炔。
