  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.
