Synthesis of the cyclopentyl nucleoside (-)-neplanocin A from D-glucose via zirconocene-mediated ring contraction

Two approaches for the conversion of D-glucose to (-)-neplanocin A (2), both based on the zirconocene-promoted ring contraction of a vinyl-substituted pyranoside, are herein evaluated (Scheme 1). In the first pathway (Scheme 1), the substrate possesses th
