U. Koert et al., STEREOSELECTIVE SYNTHESIS OF OLIGO(TETRAHYDROFURANS) - LINEAR AND CONVERGENT ROUTES TO BITETRAHYDROFURANS AND TERTETRAHYDROFURANS, Liebigs Annalen, (8), 1995, pp. 1415-1426
The ''dimeric'' and ''trimeric'' oligo (tetrahydrofurans) (oligo-THFs)
24, 28,32, and 38 were synthesized stereoselectively according to a l
inear and a convergent synthetic strategy. The oligo-THFs thus obtaine
d are important intermediates for the synthesis of artificial ion chan
nels. Furthermore, they can be used in the total synthesis of Annonace
ae acetogenins, a class of natural occurring oligo-THFs with promising
pharmacological properties.
