  Synthesis of enantiomerically pure perhydrofuro[3,4-b]pyrans and perhydrofuro[3,4-b]furans

  摘要：

  Olefinic diols, prepared from (R)-(+)-2,2-diinetliyl-1,3-dioxolane-4-carboxaldehyde via olefination and hydrolysis, were converted into enantiomerically pure hydroxy substituted tetrahydrofuran derivatives by cyclization using N-phenylselenophthalimide and BF3. The PhSe group in the C-4 position of these tetrahydrofurans was then substituted by an allyl group using allyl-tributylstannane in the presence of AIBN. The selenium promoted cyclizalions of the allyl tetrahydrofurans in which the OH and the allyl groups are trans to each other formed the enantiopure perhydrofuro[3,4-b]pyrans, while the cyclization of the allyl tetrahydrofurans in which the Off and the allyl groups are cis gave rise to the perhydrofuro[3,4-b]furans. These bicyclic products were finally deselenenylated with triphenyltin hydride and AIBN. (C) 2004 Elsevier Ltd. All rights reserved.
