  Simple Designs for the Construction of Complex trans-Fused Polyether Toxin Frameworks. A Linear Strategy Based on Entropically Favored Oxirane Ring Enlargement in Epoxycycloalkenes Followed by Carbon-Carbon or Carbon-Oxygen Bond-Forming Cyclizations

  摘要：

  A successful design for the construction of trans-fused medium-size cyclic ethers is described. The key features of the synthesis are as follows: (i) intramolecular oxirane ring expansion in cycloalkenes to give bridged oxabicyclic systems and (ii) linear, one- or two-directional synthetic operations which generate external oxocycles in single reaction steps. The general approach involves the intramolecular addition of a stable gamma-alkoxy-substituted allylstannane to an aldehyde carbonyl group, and the entire reaction is conducted in a one-pot process which includes the following: (i) vic-diol fragmentation from the bridged oxabicyclic precursor and (ii) Lewis acid-induced cyclization of the resulting aldehyde-allylic tin system. While the present strategy was mostly developed around racemic models, the potential for adoption of;enantioselective features is immediate. The versatility, scope, limitations, and potential applications of the present technology are discussed in detail.

  reported on the cyclization of (ω-hydroxy-β-hydroxyalkyl)cobaloximes (1, 2 and 3) to form 5, 6 and 7-membered ring cyclic ethers (4, 5 and 6). Reversible cyclization and eventual irreversible alkene decomplexation (to form 7, 8 and 9) varied as a function of ring size. The practical consequence is that cyclizations to form 5 and 6 membered rings are feasible whereas formation of a 7 membered ring is not.

  关于（ω-羟基-β-羟基烷基）钴肟（1、2和3）的环化以形成5、6和7元环醚（4、5和6）的研究已有报道。可逆环化和最终不可逆烯烃分解（形成7、8和9）随环大小的变化而变化。实际的结果是形成5和6元环的环化是可行的，而形成7元环的环化是不可行的。
