H. Ovaa et al., A STEREOSELECTIVE AND EFFICIENT ROUTE TO (3S,4R,5S)-(-4,5-DIHYDROXYCYCLOPENT-1-EN-3-YLAMINE - THE SIDE-CHAIN OF THE HYPERMODIFIED NUCLEOSIDE-Q()), Tetrahedron letters, 39(43), 1998, pp. 7987-7990
A stereoselective and high yielding route is described to a suitably p
rotected derivative of (3S, 4R, 5S)-(+)-3-amino-4,5-dihydroxycyclopent
-1-ene, the side chain moiety of queuosine. The synthetic route compri
ses a ring-closing metathesis (RCM) of a mannofuranose-derived diene f
ollowed by Overman rearrangement. (C) 1998 Elsevier Science Ltd. All r
