Nucleoside Analogues with a 1,3-DieneFe(CO)<sub>3</sub>Substructure: Stereoselective Synthesis, Configurational Assignment, and Apoptosis-Inducing Activity
The synthesis and stereochemical assignment of two classes of iron‐containing nucleoside analogues, both of which contain a butadieneFe(CO)3 substructure, is described. The first type of compounds are Fe(CO)3‐complexed 3′‐alkenyl‐2′,3′‐dideoxy‐2′,3′‐dehydro nucleosides (2,5‐dihydrofuran derivatives), from which the second class of compounds is derived by formal replacement of the ring oxygen atom
