Elaboration of d-(−)-Ribose into a Tricyclic, Natural Product-like Scaffold
journal contribution
posted on 2004-11-26, 00:00 authored by Roland Messer, Andrea Schmitz, Luzia Moesch, Robert HänerThe construction of natural product-like, tricyclic
compounds is reported. Starting from a d-(−)-ribose-derived
dihydrofurane, the tricyclic scaffold is prepared via an
intramolecular hetero-Diels−Alder reaction. The reaction
proceeds with very high diastereoselectivity through an endo
transition state, as established on the basis of X-ray structural analysis of the products. Further modification and
derivatization of the obtained products is described.
