  在烯丙基三正丁基锡-AIBN的存在下，环丙基甲基溴化物/黄药发生开环反应，并同时以高收率形成双键二烯丙基衍生物。用Grubbs的催化剂在双烯丙基二烯丙基衍生物上进行的闭环易位反应提供了螺环戊烯基产物。这两种方法的结合已应用于合成单，双环戊基碳水化合物以及螺环戊基脯氨酸衍生物。

  Synthesis and Application of 3,3-Spirocyclopropane Derivatives Obtained from 1,2:5,6-Di-O-Isopropylidene-α-D-Glucofuranose

  摘要：

  3,3-Spirocyclopropane derivatives (5 and 7) were prepared by three different methods of cyclopropanation starting from 1,2:5,6-di-O-isopropylidene-alpha-D-glucofuranose (2). Subsequent radical induced cyclopropane ring opening reaction stereospecifically provided the 3-C-allyl derivative (9). However, activation of the cyclopropyl ring through the aldehyde (10) followed by hydrogenation gave a quaternary chiral derivative (11) which was elaborated to the versatile intermediate (1) by using Bamford-Stevens reaction.

  In the presence of allyl tri-n-butyltin--AIBN, cyclopropylmethyl bromides/xanthates undergo ring-opening reaction with concomitant formation of geminal diallyl derivatives in good yields. The ring closing metathesis reactions on geminal diallyl derivatives with Grubbs' catalyst provided spirocyclopentenyl products. Combination of these two methodologies has been applied to the synthesis of mono-,
