    • The N-type conformation is defined as the conformation with the 3'′- carbon puckering to the same side as the 5'′-carbon. Therefore, we define 1, 2, and 8 as N-type mimics, whereas 4-7 are defined as S-type mimics.

    • The cleavage of an N3-benzylthymine-bond has been reported before using Na-naphthalate as the active reagent: Philips, K. D.; Horwitz, J. P. J. Org. Chem. 1975, 40, 1856-1858. Therefore, the synthesis of the bicyclic nucleoside target has also been approached using the N3-benzylated compound 12 in order to remove both benzyl groups in the last step. All steps were prepared in similar yields giving finally the N3-benzyl derivative of 8. However, efficient removal of the N3-benzyl group was not accomplished. See Supporting Information for details.
