4-Substituted-5(3)-carbamoyl-3(5)-(2-deoxy-β-D-ribofuranosyl)pyrazoles. Application of Palladium Catalyzed Glycal Coupling Methodology to the Synthesis of Pyrazofurin Analogs
摘要:
Analogs of the C-nucleoside pyrazofurin were prepared in 7-9 steps using a key Pd(0)-catalyzed coupling reaction between protected iodopyrazoles 6a and 6b and glycal 8 to form the glycosyl bond. Conditions for this reaction were improved from those previously described for related reactions in order to maximize product yields and eliminate the need for triphenylarsine.
