  PYRANOSIDE ALKENE TEMPLATES FOR THE SYNTHESIS OF CIS-2,5-DISUBSTITUTED TETRAHYDROFURAN SUBUNITS OF THE ACETOGENINS

  摘要：

  The iodoetherification reaction of t-butyl and trityl glycosides of C6 allylated-2,3-dideoxy-D-erythro- and D-threo-pyranosides was examined as part of a model study aimed at the synthesis of the 2,5-disubstituted tetrahydrofuran subunits found in the acetogenin group of natural products. In general, the t-butyl glycosides gave moderate, and the trityl derivatives, excellent stereoselectivity for the cis THF product.

  C-6 allylated pyranosides for the synthesis of complex oxygenated tetrahydrofurans

  摘要：

  The iodoetherification of C6 allylated D-pyranosides containing an allylic benzyloxy substituent, and their acyclic 5-hexen-, 1,2,4-triol analogs were performed. Pyranosides of R configuration at the allylic ether gave exclusively a syn,syn-2,5-dialkyi-3-oxy-tetrahydrofuran which is primed for elaboration into several classes of naturally occurring THF's. By comparison, the stereoselectivity for the non-pyranoside derivative was much lower. In the S series, the bias was opposite for the pyranoside vs, the non-pyranoside substrates, but the selectivity in both cases was low. (C) 1997 Elsevier Science Ltd.
