A Remarkably Simple Chemicoenzymatic Approach to Structurally Complex Bicyclo[3.1.0]hexane Carbocyclic Nucleosides
摘要:
[GRAPHICS]Intramolecular cyclopropanation of a carbene engendered from the corresponding diazo beta -ketoester produced the desired bicyclo[3.1.0]hexane pseudosugar. Purine nucleosides obtained via Mitsunobu coupling were resolved with adenosine deaminase. The requisite beta -ketoester was assembled in one step from ethyl acetoacetate and acrolein.
