  Synthesis of medium-sized cyclic allylic ethers by ring-closing metathesis and subsequent elaboration to sub-units found in the brevetoxins and ciguatoxins

  摘要：

  Saturated and unsaturated seven- and eight-membered cyclic ethers of the type found in the brevetoxins and ciguatoxins have been prepared in enantiomerically pure form in 10 steps from a readily available chiral pool material. The key steps in this sequence are ring-closing metathesis of allylic ethers, and subsequent elaboration of the cyclic allylic ether products by stereoselective epoxide formation and ring-opening.

  A new strategy for the enantioselective synthesis of eight- and nine-membered cyclic ethers corresponding to sub-units of brevetoxin A has been developed. The strategy involves the use of ring-closing metathesis reactions of allylic ethers to effect ring construction.
